For hotel bathrooms, specify a sealed GFRC basin with water absorption of 1% or less, a rim flat to 1 mm, a waste outlet that matches your tapware supplier, a clear decision on overflow, and a housekeeping regime with pH-neutral cleaners only. Approve the colour and the sealer on a mock-up room before production.
Concrete basins give a hotel bathroom the warmth of stone at a fraction of the weight and with full control over colour. They also behave differently from ceramic, so the specification has to cover sealing and cleaning, not only size.
Basin types used in hotels
| Type | Example | Typical use |
|---|---|---|
| Round or oval vessel | QF Alba, QF Norma | Guest rooms with a solid vanity top |
| Pill or rectangular vessel | QF Jada, QF Otti | Double vanities, suites |
| Half-round fluted basin | QF Valentina | Powder rooms, public toilets |
| Basin with tap deck | QF Blanca | Deck-mounted tapware, compact rooms |
| Integrated vanity top | Cast to drawing | Brand-standard rooms in phased rollouts |
Specification checklist
| Item | What to write |
|---|---|
| Material | GFRC, polymer-modified, sealed; absorption ≤ 1% after sealing |
| Dimensions and tolerance | Outer size ± 3 mm; rim flatness 1 mm over the full length |
| Waste | Outlet diameter and pop-up type from your tapware schedule |
| Overflow | With or without; local code and brand standard decide |
| Tap holes | None, one or three, with positions dimensioned |
| Colour | Stocked colour code or Pantone match with retained chip |
| Sealer | Penetrating plus top-coat, stain-tested against coffee, wine and cosmetics |
| Weight | Per piece, so the vanity and fixings are sized correctly |
| Packing | Individual crate, labelled by room type and floor |
The material reasoning is in GFRC vs cast concrete vs terrazzo.
Sealing and housekeeping
A sealed concrete basin resists everyday staining, but acids and bleach attack the cement surface. Give housekeeping a one-page card: pH-neutral cleaner, soft cloth, no abrasive pads, no bleach or descaler on the basin, rinse after hair dye or self-tanner spills. Plan a light re-seal every one to two years in high-occupancy rooms; it takes minutes per basin.
Writing basins into the BOQ
- One line per basin type and colour, with room-type quantities.
- Separate lines for spares (we suggest 2–3%) and the mock-up set.
- Delivery phase per floor if the fit-out is phased.
- Attach the tapware schedule so waste and tap holes match.
Our hospitality and contract projects team quotes line by line from your BOQ, with shop drawings and a mock-up before production. Indicative basin prices start around $65 FOB; see the price guide.
FAQ
Do concrete basins stain?
A properly sealed basin resists coffee, wine and cosmetics for normal cleaning intervals. Acids and bleach can etch the surface, so housekeeping must use pH-neutral cleaners.
How heavy is a concrete basin?
A GFRC vessel basin typically weighs 8–15 kg; large integrated vanity tops 25–32 kg. Cast concrete versions weigh roughly 40% more.
Can a concrete basin have an overflow?
Yes. The overflow channel is cast into the basin and has to be decided before the mould is made, so confirm it with the tapware schedule.
How often should a hotel reseal concrete basins?
Every one to two years in high-occupancy rooms, or when water no longer beads on the surface.
