Grohe UNISET — Concealed Tank with EPS Foam Housing for Pakistan's Hidden Toilet Installations
A concealed tank is a water cistern that hides completely inside the bathroom wall — the tank, the water supply connection, and all plumbing are permanently enclosed within the wall structure. From outside, you see only the wall-hung toilet bowl floating above the floor and a flush plate flush with the tile surface. No visible cistern. No exposed pipes. No floor contact. This is the wall-hung bathroom specification that Pakistan's premium residential market, five-star hotels, and luxury commercial projects are increasingly adopting.
The Grohe UNISET makes this installation faster and simpler than any open-frame concealed tank system. The reason is the EPS housing — the grey expanded polystyrene foam block visible in the product photograph. In a conventional concealed tank installation, you install the steel frame, then build a separate partition wall of blockwork or drywall around it, then waterproof and tile the wall. The UNISET eliminates the partition wall construction step entirely. The EPS foam block IS the partition. You position the UNISET against the structural wall, fix it, plumb it, and tile directly onto the EPS foam face. The foam block provides structural stability, thermal insulation, and acoustic dampening — and the tile adhesive bonds directly to it. Faster, simpler, one fewer trade involved.
The 3-component set includes everything for the concealed tank and its wall installation: the UNISET with GD 2 cistern and EPS housing (art. 38 643 001), the Grohe Skate Air Chrome flush plate in vertical orientation (art. 38 505 000), and the support feet (art. 37 304 000). The wall-hung toilet bowl is sold separately — contact Sardar & Co at 0300-0341288 for compatible recommendations.
Available exclusively through Sardar & Co, Pakistan's authorised Grohe distributor.
Component 1 — Article 38 643 001: UNISET Concealed Tank with EPS Housing
The main unit — the grey foam block shown in the product photograph. The EPS housing encases the steel support structure and the GD 2 dual-flush cistern (water tank). 480mm wide, 1110mm total height. Installation depth 15–70mm adjustable, maximum 130mm. The Grohe logo is embossed on the EPS face. The white GD 2 cistern with Grohe branding is accessible at the top of the EPS face for commissioning. Wall-fixing brackets at the top anchor the unit to the structural wall. The entire plumbing assembly — cistern, water supply connection, soil pipe connector — is permanently concealed once the tile is applied to the EPS face.
Component 2 — Article 38 505 000: Grohe Skate Air Flush Plate, Chrome, Vertical Installation
The Skate Air in Chrome configured for vertical (portrait) installation — the only visible component of the completed installation on the tiled wall surface. Chrome coordinates with the widest range of bathroom hardware finishes. If a different finish or the Skate Cosmopolitan profile is required, Grohe Skate flush plates are available separately at Sardar & Co. Contact 0300-0341288 for alternatives.
Component 3 — Article 37 304 000: Support Feet
Adjustable floor-contact feet that stabilise the UNISET unit during installation before final fixing. Accommodate minor floor surface variations during positioning.

What Is EPS and Why Does It Matter for a Concealed Tank Installation
EPS stands for Expanded Polystyrene — the same lightweight cellular foam material used in packaging, thermal insulation, and building construction. In the context of the UNISET concealed tank, the EPS performs a role that no other material in the competing open-frame systems does: it replaces the partition wall entirely.
In a standard open-frame concealed tank installation (such as the Grohe Rapid SL), the process is: install the steel frame → build a blockwork or drywall partition around it → waterproof and tile the partition. Three distinct construction phases, often three different trades.
With the UNISET EPS housing, the process is: install the UNISET → tile directly onto the foam face. Two phases. The EPS block provides the structural surface that the tile adhesive bonds to, the thermal barrier that prevents condensation on the cistern body from reaching the tile face, and the acoustic layer that dampens cistern refill noise. In a multi-unit residential development or hotel project specifying 20, 50, or 100+ concealed tank installations, the elimination of the partition wall build step across every unit is a significant programme and cost efficiency.
Grohe UNISET vs Grohe Rapid SL — Which Concealed Tank Is Right for Your Project
Two Grohe concealed tank systems are available at Sardar & Co. The correct choice depends entirely on the installation method and project programme:
Grohe UNISET (this product) — EPS foam housing. Tile directly onto foam. No separate wall needed. Faster programme. Built-in insulation. Skate Air Chrome vertical flush plate. Support feet for freestanding positioning. The correct choice for projects prioritising installation speed and construction simplicity.
Grohe Rapid SL 3-in-1 — open steel frame. Requires a separate partition wall built around the frame. More flexibility in partition wall material. Skate Cosmopolitan Chrome flush plate. Wall brackets for structural fixing. The correct choice for conventional new-build construction where the partition wall is being built to specification regardless of the concealed tank installation.
Where the Grohe UNISET Performs Best
Multi-unit residential and hotel projects — programme efficiency
For developers specifying 10, 50, or 100+ concealed tank installations across a residential development or hotel project, the UNISET's elimination of the separate partition wall construction step delivers measurable programme savings per installation. The EPS block replaces the partition builder entirely. At project scale, this is a significant cost and time advantage. Contact Sardar & Co at 0300-0341288 for project-scale pricing on the Grohe UNISET.
Renovation retrofits — faster bathroom upgrades
For renovation projects converting existing bathrooms to wall-hung concealed tank installations, the UNISET's self-contained EPS housing simplifies the work considerably. Rather than demolishing an existing wall and rebuilding a partition to accommodate a steel frame cistern, the UNISET can be positioned against the structural wall with its foam housing providing the new finished wall face. Faster renovation cycles, less disruption to the rest of the property.
Premium new-build residential — simplified specification
For new-build premium residential bathrooms where the architect wants the simplest possible concealed tank specification, the UNISET delivers a pre-assembled, self-contained unit: position, fix, plumb, tile, fit bowl, fit flush plate. Six steps, all completed by one or two trades. The foam face is the finished partition surface — no additional partition materials required between the UNISET and the tile adhesive.
Five-star hospitality bathrooms
Pakistan's five-star hotel sector specifying concealed tank installations for suite and guest bathrooms benefits from the UNISET's construction efficiency at the site management level. The Grohe brand name on the concealed tank communicates the same international premium specification standard that international hotel brand consultants require — Grohe UNISET is specified in hospitality projects globally.

Frequently Asked Questions
What is a concealed tank and how does the Grohe UNISET work?
A concealed tank is a toilet water cistern installed completely inside the bathroom wall — the tank, supply pipe, and all plumbing are permanently hidden. The Grohe UNISET houses the GD 2 concealed tank within an EPS foam block. You position the UNISET, fix it to the structural wall, plumb the water supply and drain connections, then tile directly onto the foam face. The result: a wall-hung toilet bowl floating above the floor with only a flush plate visible on the tile wall — no tank, no pipes, no floor contact. Available exclusively through Sardar & Co Pakistan. Call 0300-0341288 for pricing.
What is EPS foam housing and why does it replace a partition wall?
EPS (Expanded Polystyrene) is the grey foam material that forms the UNISET's outer block. In standard concealed tank installations with open steel frames, a separate blockwork or drywall partition must be built around the frame before tiling. The UNISET's EPS foam block IS the partition — the tile adhesive bonds directly to the foam surface. This eliminates the partition wall construction phase entirely, saving programme time and reducing the number of trades required per installation.
What does the Grohe UNISET set include?
Three components: (1) UNISET with GD 2 concealed tank and EPS foam housing, art. 38 643 001; (2) Grohe Skate Air flush plate Chrome vertical, art. 38 505 000; (3) support feet, art. 37 304 000. The wall-hung toilet bowl is NOT included — sold separately. Contact Sardar & Co at 0300-0341288 for compatible bowl recommendations.
What are the installation dimensions of the Grohe UNISET?
Confirmed from the technical drawing: 480mm wide, 1110mm total height, bowl fixing height 830mm, installation depth 15–70mm adjustable (max 130mm), maximum overall depth with bowl 620mm, drain at 116mm (Ø90) or 126mm (Ø110) above finished floor, bowl fixing centres 220/320mm.
What drain pipe size does the Grohe UNISET accept?
Two options: Ø90mm drain pipe with centre at 116mm above finished floor, or Ø110mm drain pipe with centre at 126mm above finished floor. Confirm your drain pipe size with your plumbing contractor before rough-in positioning.
What is the difference between the Grohe UNISET and the Grohe Rapid SL?
Both are Grohe concealed tank systems for wall-hung toilet installations. UNISET: EPS foam housing — tile directly on foam, no separate partition wall, faster installation, Skate Air Chrome vertical flush plate. Rapid SL 3-in-1: open steel frame — separate partition wall required, Skate Cosmopolitan Chrome flush plate. Choose UNISET for speed and simplicity; choose Rapid SL for conventional partition construction.
