BANARTA
XPS-based tile backing for bathroom projects
This bathroom backer board combines an extruded polystyrene foam core with fiberglass and cement-based surfaces. Specify the board for your tiled wall, floor or enclosure together with the supporting construction and finishing system.
Confirm the available thickness and dimensions for the intended installation. The board is one component of the bathroom assembly, not a substitute for detailing its joints and waterproofing connections.

Bathroom details to confirm
- Walls: support spacing, fixings, thickness and permitted tile loading.
- Wet-area sealing: board joints, internal corners, pipe penetrations and wall-to-floor connections.
- Floors: substrate preparation, adhesive or fixing method, and any heating-system requirements.
- Enclosures and shelves: drawings, supports and approved construction details.
- Finishes: tile and adhesive compatibility with the board surface and sealing system.
Follow the matched installation instructions. The board alone does not make a shower or bathroom watertight; confirm all sealing components and connections before installation.
Discuss your bathroom project
Send the board dimensions, thickness, application, quantity and delivery destination. Include any project approval, packaging or private-label requirements.
Compare the XPS tile backer board and XPS foam tile backer board specifications before selecting the construction.
Prepare a bathroom project supply schedule
For repeated bathroom layouts or phased project deliveries, group the required boards by room type, wall or floor location, finished thickness and piece count. Reference the current drawing revision and mark any proposed cut-outs or shaped parts for confirmation.
Separate board supply from the specified joints, corners, fixings and penetration details. List the sealing components required by the approved assembly and ask which items are included in the quotation. A board quotation alone does not establish that a complete bathroom waterproofing kit is supplied.
- Identify the substrate, board support and intended tile finish for each room type.
- Request a sample of the quoted board configuration, with the applicable installation and test documents.
- Confirm available sizes and thicknesses, quantities per pack, edge protection and delivery labels for each project batch.
- State the delivery destination and required schedule; confirm sample arrangements, minimum quantity and lead time with the quote.
Request a bathroom backer board project quotation. Prepare the wet-area joint and penetration details and review the sample and packing checks before approving bulk supply.
See the XPS tile backer board range for other coated and grooved constructions. Product names alone do not establish a different board grade; compare the actual configuration and documents.
