Roca In-Wash® Collection · In-Tank® Series
Vorea In-Tank® Back-to-Wall
Floorstanding Smart Toilet
There is a particular category of bathroom fitting that announces itself through restraint rather than specification. The Roca In-Wash® Vorea In-Tank® belongs to this category. From across the room, it reads as a beautifully resolved back-to-wall WC in the established European tradition. Only on closer inspection does the full extent of its capability become apparent: rear and front warm-water washing, Coanda Effect precision drying, a heated seat, UV-assisted nozzle hygiene, Rimless® Vortex flushing, and a complete smart-home control platform, all integrated without the slightest visual compromise.
The defining engineering decision is the In-Tank® cistern, which is incorporated directly into the body of the toilet rather than specified as a separate concealed-frame system. This is not a marginal distinction. It changes what the installation looks like, how it installs, and—critically—what it communicates to anyone who uses the bathroom. Complexity, in the best products, disappears entirely. The Vorea In-Tank® achieves precisely this.
Model A803505001 is the floorstanding back-to-wall configuration, featuring a dual-outlet waste arrangement that accommodates both floor and wall waste connections. It requires only a cold water inlet and a standard 230V power supply. The entire smart-toilet experience—daily comfort, long-term hygiene, and intuitive control—is self-contained within a single product.
Why the Vorea In-Tank® suits the most considered UK bathroom projects
The question most asked of premium smart toilets is whether they can hold their own aesthetically in bathrooms where the standard of everything else is high. The Vorea answers this question convincingly. Its proportions are those of a quality floorstanding WC rather than a consumer electronics product. The In-Tank® system removes the one element—a visible cistern or frame—that most commonly dates a smart toilet installation. And the Rimless® bowl means there is no underrim area to harbour residue, making the cleaning regimen as discreet as the product itself.
For interior designers, bathroom specialists and discerning private clients who have already decided that personal hygiene deserves the same quality of engineering as everything else in the home, the Vorea In-Tank® represents a coherent and fully resolved answer.

Technology & Features in Detail
The cross-section reveals what distinguishes the Vorea In-Tank® from both conventional smart toilets and standard back-to-wall WC installations. The cistern occupies a chamber within the body of the toilet itself, sharing the ceramic housing with the smart-seat technology, the Rimless® Vortex flush system, and the internal water-heating element.
The practical consequence is significant. There is no concealed cistern frame to design around, no flush plate to specify, no secondary component that risks visual inconsistency with the pan. The entire installation—from floor to top of cistern—is a single, coherent object. It is an approach that demands considerably more from the product engineer and considerably less from the bathroom designer.
Specification note: the In-Tank® format eliminates the need for a separate SLK or concealed-frame module, simplifying both the specification process and the installation timeline without any functional compromise.
The Vorea employs distinct nozzle outlets for rear and front wash functions rather than a single compromise arrangement. This allows each function to be appropriately positioned and calibrated, producing a meaningfully better cleansing result than a single nozzle operating in both modes.
Water is heated internally on demand, so the warm-water supply is immediate and consistent throughout the wash cycle without any dependence on a household hot-water system. Pressure and temperature are independently adjustable for each function through the remote or the Roca Connect app.
- Independent rear wash and front wash outlets, each precision-positioned
- Instant warm water from the internal heater — no hot-water connection required
- Individually adjustable water pressure and temperature per function
- Suitable for daily use as a complete replacement for conventional paper hygiene
The Coanda Effect describes the tendency of a fluid jet—in this case, a directed airstream—to follow a curved surface rather than dispersing into the surrounding environment. Applied to a dryer, this means the air reaches the target area with significantly greater efficiency than a conventional warm-air fan, which disperses energy broadly and indiscriminately.
In practical terms, the Coanda system achieves comparable drying results at lower heat settings and in less time. The experience is noticeably more refined: less of a fan sensation, more of a directed, calm warm-air finish. Both temperature and intensity are adjustable, allowing the user to arrive at the result that suits them rather than accepting a manufacturer's preset.
For daily-use buyers: the quality of the dryer is the single factor most frequently cited by smart-toilet owners when reflecting on their purchase. Coanda Effect drying is a meaningful step above the standard warm-air systems found in the majority of smart toilets at or below this price point.
The Vorea's heated seat is calibrated for comfort rather than spectacle. The temperature range is broad enough to accommodate personal preference across seasons, and the adjustment is accessible from both the remote and the app. The seat and cover are constructed from antibacterial material with a soft-close mechanism.
What the seat does not do is call attention to itself aesthetically. The proportions remain those of a quality WC seat rather than a piece of consumer electronics. In a bathroom where the quality of the other fittings is high, this restraint is exactly what is required. The heated seat serves the user without compromising the room.
- Adjustable seat temperature via remote or Roca Connect app
- Antibacterial seat and cover materials as standard
- Soft-close mechanism on both seat and cover
- Energy-saving standby mode reduces power draw during periods of non-use
The nozzle system operates a dual-stage cleaning cycle automatically before and after each use. A water-based rinse removes surface contamination; UV-assisted treatment then addresses bacterial presence that water alone does not eliminate. The result is a nozzle that enters each use cycle already sanitised—a standard that distinguishes serious smart-toilet engineering from more rudimentary water-rinse-only solutions.
The nozzle tip is removable without tools, allowing straightforward periodic manual cleaning as part of the bathroom's ordinary maintenance routine. This is a practical detail that matters increasingly over the years of ownership, particularly in hard-water areas where mineral deposits can accumulate at contact surfaces.
UV sanitisation note: UV-C light at the wavelengths used in the Vorea's nozzle system eliminates the majority of common bathroom bacteria without chemical additives, without residue, and without any user intervention. It operates automatically as part of the post-use cycle.
The Rimless® bowl design eliminates the conventional underrim channel from which water enters the bowl in a traditional WC. That channel is, by design, inaccessible to a cleaning brush and by consequence a reservoir for residue and bacterial growth. Removing it simplifies cleaning to a single, unobstructed bowl surface.
The Vortex flush pattern distributes water in a rotating 360° movement across the bowl surface, achieving comprehensive coverage without the volume of water that a conventional flush requires. The dual-flush In-Tank® system operates at 4.5 and 3 litres respectively, balancing flushing performance against water economy. The overall noise level is significantly below that of a standard cistern flush, which is a material benefit in bathrooms adjacent to bedrooms or open-plan living areas.
The Vorea incorporates an active carbon deodorising system that operates during and immediately after use, drawing bathroom air through a filter that adsorbs odour molecules before they disperse into the room. The mechanism is quiet, automatic, and—like all the best product features—entirely invisible to the user.
For en-suites directly adjacent to bedrooms, and for frequently used family bathrooms, an effective deodoriser transitions quickly from a specification curiosity to an indispensable feature. Active carbon filtration is considerably more effective than simple air circulation and does not require chemical cartridges or periodic replacement of chemical components.
The Vorea is operated through three independent control modes: the supplied remote handset, the side button on the unit itself, and the Roca Connect application for iOS and Android. The remote handles day-to-day preferences comfortably. The side button provides access to core functions without requiring the remote—a practical consideration for guest bathrooms and for situations in which the remote has been misplaced. The app extends the experience into personalisation territory that a remote cannot reach.
Through Roca Connect, each member of a household can store their own preferred wash pressure, water temperature, seat heat level, and dryer settings as a named profile. The app also manages maintenance scheduling—descaling reminders, filter status, and function logs—removing the requirement for the user to track the toilet's maintenance history independently.
- Three independent control modes — remote, side button, and app
- Per-user preference profiles storable in the Roca Connect app
- Maintenance scheduling and system status accessible through the app
- The toilet operates completely without smartphone connectivity if preferred
The integrated night light provides soft, low-level illumination after dark without activating the full seat system or requiring the bathroom's main lighting. Combined with the built-in user-detection sensor—which opens the lid automatically as the user approaches—the result is an experience that feels calm, responsive and properly thought through rather than gadget-like.
These are features whose value is felt in the everyday rather than in the showroom. The night light prevents the brief disorientation of navigating an unfamiliar bathroom light switch in darkness. The lid sensor removes a small but daily physical interaction. Neither is transformative in isolation; together with the rest of the product's capabilities, they contribute to a bathroom experience that is perceptibly more considered than the conventional alternative.
Any smart toilet contains internal water channels, heating elements and nozzle pathways that are susceptible to limescale accumulation over time. In the United Kingdom, where mains water hardness varies considerably by region—from the notably soft water of Scotland and the North West to the exceptionally hard water of London, the Home Counties and East Anglia—this is not a theoretical concern but a practical certainty that affects performance if left unaddressed.
The Vorea includes a built-in descaling programme that treats the internal water pathways without requiring disassembly, chemical products, or specialist intervention. The cycle is initiated through the remote or the Roca Connect app on a schedule determined by local water hardness. For buyers installing in hard-water areas, this is one of the most consequential long-term ownership features and one that is absent from a significant proportion of smart toilets at this price level.
Maintenance recommendation: for London and south-east England installations, the descaling programme should typically be run every four to six weeks during the first year of ownership. Interval adjustment can be managed through the Roca Connect app based on observed performance.
Design & Finish
The test that premium bathroom products face in practice is whether they can hold their own when the standard of everything around them is genuinely high. In bathrooms specified to a standard that extends to bespoke joinery, large-format stone and premium sanitaryware collections, a product that reads as a technology import rather than a considered design choice fails this test immediately.
The Vorea passes it. The proportions are right. The surface quality is appropriate. The absence of visible technology—no trailing cables, no external cistern, no compromise silhouette—allows the product to sit within the room rather than demanding attention from it. This is the result of a design process that began with the aesthetic outcome and worked backwards through the engineering, rather than the reverse.
The remote handset supplied with the Vorea In-Tank® is designed to be left in a bathroom without apology. The horizontal layout distributes the control functions in a logical sequence that reflects the order in which they are actually used, and the physical format is compact enough to fit within a standard wall-mounted remote holder without dominating the room.
The button layout separates the most frequently used functions—wash mode, pressure, temperature, dryer—from the less frequently adjusted settings, meaning the daily interaction requires no learning curve after the first week of use. For households less inclined towards app-based control, the remote provides access to the full functional range of the product with nothing more than physical buttons and a brief read of the supplied guide.
Practical note: the supplied remote is wall-mountable and can be positioned at a height and location determined at the time of installation. This is worth considering during first-fix planning, as a well-placed remote makes the day-to-day experience significantly more comfortable for every member of the household.
The conventional approach to installing a floorstanding smart toilet involves pairing the pan with a separate concealed cistern system—a frame, an in-wall cistern module, flush plate, and the associated set of specification decisions and potential aesthetic inconsistencies between components from different manufacturers.
The In-Tank® system removes this entire layer of complexity. The dual-flush mechanism at 4.5 and 3 litres operates within the body of the toilet itself and is actuated through the product's own control system rather than a separate flush plate. The result, visually, is a back-to-wall toilet with no visible cistern, no flush plate, and no external control mechanism beyond the remote. For bathrooms where the wall surface behind the toilet is to remain uninterrupted—a common requirement in contemporary stone and tile installations—this is a particularly valuable characteristic.
The nozzle canula is the component with which the product's hygiene claim must ultimately be justified, and it is engineered accordingly. The material selection reflects antibacterial requirements. The geometry of the outlet positioning reflects the functional difference between rear and front wash. The retraction mechanism ensures the nozzle remains within the seat housing between uses, protected from the bowl environment and from contact with other surfaces.
The removable tip—which Roca has designed to detach and reattach without tools—is a detail that reveals the product's approach to long-term ownership rather than just the initial purchase experience. A nozzle tip that cannot be cleaned properly is one that will accumulate mineral deposits and compromise hygiene performance over time, regardless of how sophisticated the UV sanitisation cycle. The Vorea addresses this directly.
Viewed from the side, the Vorea In-Tank® presents the profile of a quality back-to-wall WC rather than a smart-toilet product. The seat height is appropriate to a premium residential context. The cistern volume is contained within the ceramic housing without creating the bulked-up rear profile that characterises lesser integrated-cistern designs. The overall depth from wall to front of seat is proportioned correctly for back-to-wall installation against a tiled surface.
These are details that matter in rooms where a side-on view is the primary one—an en-suite entered from the bedroom end of the room, for example, or a principal bathroom viewed from the bath. The Vorea does not require its technology to be hidden from this angle, because the technology has been designed not to show.
For design professionals: the Vorea's profile dimensions are available on request from our specification team. For bathroom renders and client presentations, we can supply product images in multiple orientations against neutral backgrounds on request.
The Vorea In-Tank® is specified most comfortably alongside bathroom collections in which quality, coherence and architectural finish are the primary criteria. It sits naturally with premium sanitaryware ranges from European manufacturers—Duravit, Geberit, Villeroy & Boch, Laufen—without creating the impression that the WC has been sourced from a different design world than the basin, bath or shower enclosure.
Its surface quality is consistent with a product at this level. The glaze is even. The ceramic weight is appropriate. The seat and cover close with the damped, unhurried movement that clients at this market level have come to expect as a baseline. None of this is remarkable in isolation. Taken together, it means the product does not introduce a quality inconsistency into the specification—which, in a bathroom where everything else has been selected with care, is the most important thing a WC can achieve.

Installer & Specifier Notes — A803505001
The following notes are intended for installation professionals, interior designers and bathroom specialists specifying the Vorea In-Tank® as part of a new build or renovation project.
- First-fix services: a cold water supply and a fused 230V electrical socket are required during first fix. Unlike wall-hung smart toilet installations, no concealed cistern frame is required — the toilet is self-supporting. The electrical socket and water stub should be positioned to align with the toilet's rear connection points; our technical team can provide the relevant positioning dimensions on request.
- Waste configuration: the dual-outlet arrangement should be confirmed with the client and plumber prior to first fix, as the floor or wall waste decision affects the sub-floor or chase routing required. Both configurations are equally practical; the choice is determined by the existing or planned service layout.
- Hard water areas: for installations in London, the south-east, the East Midlands and East Anglia, brief the client on the integrated descaling programme before handover and recommend an initial interval of four to six weeks. This can be adjusted through the Roca Connect app as the client develops familiarity with their local water conditions.
- App setup at handover: configure the Roca Connect app and walk the client through at least one user profile before leaving site. The setup process takes approximately five minutes and materially improves first-week satisfaction, particularly for clients who have not used a smart toilet previously.
- Remote positioning: the remote is wall-mountable and its position is best confirmed with the client at installation stage rather than left at the point of installation. A remote mounted at an ergonomically considered height, on the wall most naturally reached from the seat, removes a daily friction point that is otherwise easy to overlook.
Demonstrate removal and replacement of the nozzle tip to the client during handover. Monthly tip cleaning—alongside the automatic UV cycle—is the recommended standard for optimal long-term nozzle hygiene in residential use.
Ensure the client is aware that the side button on the unit provides access to essential washing and flushing functions independently of the remote. This is the relevant control method for guests who are unfamiliar with the remote.
Questions & Answers
The Vorea In-Tank® is a complete, integrated product rather than a smart seat module mounted to a standard pan. This distinction matters in three respects: aesthetically, the two components do not read as a single object in the way a properly integrated smart toilet does; functionally, an add-on seat does not benefit from the engineering relationship between the seat system, the bowl geometry, and the flush technology; and practically, the installation of a separate-seat solution requires considerably more attention to compatibility between components from different manufacturers.
The In-Tank® version offers a cleaner installation outcome in settings where a floorstanding format is preferred or required. It removes the specification and installation complexity of a separate concealed cistern system—no frame, no separate in-wall cistern module, no flush plate decision. The toilet is a self-contained unit that requires only cold water and a power supply. For renovation projects where opening the wall is impractical, or for new builds where the client's preference is for a floorstanding format, the In-Tank® is the more straightforward and more resolved specification.
No. The Vorea heats all washing water internally on demand using its own instantaneous heater. The installation requires only a standard cold water inlet and a 230V electrical supply. There is no connection to the household hot water system, no thermostatic mixing valve, and no dependency on water pressure from a cylinder or boiler. This simplifies both the specification and the ongoing maintenance of the installation.
Yes. The A803505001 features a dual-outlet arrangement that accommodates both floor and wall waste configurations. The relevant configuration is selected during installation and should be confirmed with the plumber at first-fix stage, as the choice affects the sub-floor or chase routing required. Both configurations are equally supported and do not affect any aspect of the product's functionality.
No. The toilet operates completely through the supplied remote handset and the side button on the unit, with no requirement for a smartphone or an active internet connection. The Roca Connect app extends the experience with per-user preference profiles, maintenance scheduling and more granular function control, but its absence does not limit any of the toilet's core functionality. It is an enhancement for those who want it, not a dependency for those who do not.
For installations in London, the south-east, and parts of the East and East Midlands, where mains water hardness regularly exceeds 300 ppm, the descaling programme is one of the most consequential long-term ownership features. Limescale accumulation within internal water channels is not a theoretical risk but a practical certainty in these areas, and it affects heating element efficiency and nozzle flow performance progressively over time if left unaddressed. The integrated programme—accessible from the remote or the app and requiring no disassembly or chemical products—is a straightforward and effective way of maintaining performance over a five- or ten-year ownership period.
It is designed specifically for that context. The product's proportions, surface quality, and the complete absence of visible technological elements—no external cistern, no trailing cables, no flush plate on the wall—allow it to sit within a premium bathroom specification without introducing a design inconsistency. Our team is available to provide specification documentation, product imagery for renders, and a comparison with relevant alternatives if you are making a final decision between shortlisted products.
