How to Specify Marble Kurnas for Wet Areas: Drainage, Height, Stone and Installation
All For Hamam Team18 May 2026 8 min read
A practical specification guide for architects, spa consultants and hotel technical teams sourcing marble kurnas for wet hammam spaces.
Why kurna specification matters in wet hammam spaces
A marble kurna is not just a decorative basin. In a hammam, spa wet room, mosque ablution area or hotel treatment suite, it affects water movement, guest flow, cleaning access, wall details, plumbing coordination and the visual identity of the entire wet area. A weak specification can create late questions for the contractor; a clear specification helps the architect, plumber, stone supplier and operator work from the same file.
This guide is written for architects, interior designers, spa consultants, mosque project teams and hotel technical departments preparing a marble kurna specification for B2B sourcing. It does not replace local code, installer review or plumbing drawings. Use it as a project checklist before issuing an RFQ.
Stone selection and project positioning
All For Hamam's marble range includes kurnas, exclusive kurnas, marble washbasins and broader marble products. Existing site content references Turkish marble options, custom marble dimensions, marble samples, technical data sheets and CAD references on request.
For wet areas, the first decision is not only color. Confirm the design role of the stone:
Natural marble for classic hammam, hotel spa and mosque projects.
White, beige and grey Turkish marble varieties where the project needs a calmer architectural base.
Onyx or travertine only where the selected product data and project detailing support that material choice.
Custom carved kurnas for signature spa rooms or prestige mosque areas.
Visual consistency across kurna, wall cladding, flooring, washbasins and fountains.
Natural stone varies by block and cut. Ask for current material photos or samples when color, veining and tone continuity matter to the project.
Drainage and plumbing questions before ordering
Drainage should be settled before production, not after the kurna arrives on site. The supplier can provide product options, but the project team must confirm the plumbing route, local code, waterproofing system and installer requirements.
Ask these questions before ordering a hammam kurna from Turkey:
Is the kurna decorative, functional for water filling, used for treatment workflow or used in a mosque ablution sequence?
Where is the water supply located: wall, deck, concealed pipework or exposed traditional faucet?
Is the drain expected through the kurna body, floor, wall zone or adjacent wet-room drain?
Does the floor slope move water away from guest circulation and therapist working areas?
Has the waterproofing contractor reviewed penetrations, sealants and stone contact points?
Does the cleaning team need rear, side or underside access?
If these answers are not yet in the project drawings, mark them as "to be confirmed with installer/project team" in the RFQ.
Ergonomics: height, wall relationship and guest flow
There is no universal kurna height that fits every wet room. A mosque ablution line, a hotel hammam suite and a treatment-room kurna all have different body positions, water use and guest flow. The architect should confirm height with the operator, plumber and installer using the final floor build-up and wall finish thickness.
Key ergonomic checks:
User posture: seated, standing, therapist-assisted or multi-user.
Wall relationship: recessed niche, freestanding feature, against marble cladding or under a fountain/faucet.
Reach zone: faucet, bowl edge, ladle, copper bowl or foam bucket should be usable without awkward movement.
Guest flow: the kurna should not block entry, exit, towel movement or therapist circulation.
Cleaning access: staff should be able to rinse and inspect the area without moving heavy objects.
Where a product page provides dimensions, use those values in the specification. Where custom dimensions are requested, share drawings and ask the supplier to confirm feasibility.
Installation coordination
A wet-room kurna needs coordination between four parties:
Architect/interior designer: position, material direction, wall/floor relationship and visual intent.
Contractor: substrate, waterproofing, lifting access, fixing method and sequencing.
Plumber: water supply, faucet position, drainage and local compliance.
Stone supplier: product size, stone type, finish, packaging, export and material samples.
Do not treat installation as a final-site question. The kurna affects floor slope, wall cladding setting-out, faucet height, waterproofing detail and access for future maintenance.
Packaging and export questions
International projects should confirm packaging early. Marble is heavy and fragile; the RFQ should ask how the kurna will be packed, marked and documented for export. Confirm destination, Incoterms preference, unloading conditions, crate labeling, project reference, site contact and whether the shipment includes related marble pieces, faucets or accessories.
For hotel, spa and mosque projects, separate the RFQ into opening stock, stone pieces, accessories and any material samples or technical drawings needed by the project team.

What to confirm
Why it matters
Kurna type
Standard kurna, exclusive carved kurna, washbasin or custom stone piece
Keeps design intent and supplier scope aligned
Stone
Marble color, block tone, onyx/travertine only where supported by selected product data
Controls visual consistency and buyer expectations
Dimensions
Published product dimensions or custom drawing dimensions
Prevents conflicts with wall, floor and guest circulation
Drainage
Drain route, floor slope, waterproofing detail and installer responsibility
Avoids late wet-room coordination issues
Faucet relationship
Wall, deck, concealed or traditional faucet position
Affects reach, splash, wall cladding and maintenance
Height
Final height after floor build-up and installation method
Controls ergonomics for guests, staff and ablution use
Finish
Surface finish and edge treatment to be reviewed with project team
Impacts cleaning, hand feel and visual result
Packaging
Crate, labeling, destination, unloading and export documentation
Reduces risk for international transport
Samples/drawings
Material samples, technical data sheets or CAD references where needed
Helps architects approve the specification before order
A marble kurna is a stone basin used in hammam, spa and ablution settings. It can be decorative, functional or part of a treatment workflow depending on the project.
Can marble kurnas be custom sized?
Existing site content states that custom marble dimensions are available. Share technical drawings or measurements so feasibility can be confirmed.
Which stone should I choose for a hammam kurna?
Natural Turkish marble is the core choice. White, beige and grey marble are referenced on the site; onyx or travertine should be selected only when the product data and design detailing support it.
Who should confirm drainage?
Drainage should be confirmed by the architect, plumber, waterproofing contractor and installer. The supplier can support product information, but local project detailing must lead.
Can architects request drawings or samples?
The architect page references technical data sheets, material samples and CAD references on request. Include those needs in the RFQ.
