Cork Flooring for Bathrooms

Cork can be a warm, comfortable bathroom floor when you use glue-down cork tiles, prepare the subfloor properly and seal the surface with water-based polyurethane. Cork contains suberin, a natural waxy substance that helps it resist water, and a sealed tile floor has no grout lines to scrub.

Is cork right for your bathroom?

Your bathroom	Our advice
Powder room, half bath or a family bathroom with an exhaust fan	Good fit for sealed glue-down cork tiles.
Full bathroom with a tub or shower	Glue-down tiles, sealed with two coats, with bath mats and a working fan. Wipe up standing water.
Wet room, curbless shower floor or a room that is regularly flooded	Not recommended. Use a tiled shower pan and cork outside the wet zone.

Why glue-down tiles, not floating planks

Glue-down tiles are solid cork, bonded edge to edge and sealed across the whole surface, so water has no open click joints to reach. Floating planks have a fibreboard core and are better suited to the rest of the house.

Moisture and subfloor prep

1. Use a suitable substrate: concrete at or above grade, cement backer board, or smooth, sound plywood. OSB and fibreboard are not suitable.
2. Make it smooth and clean: sand, patch and remove old flooring, paint and adhesive. Over ceramic tile, a Portland-based leveling compound is a job for a professional.
3. Galvanized screws or nails reduce rust risk where leveling compound or moisture is present.
4. On concrete, run a concrete moisture test before ordering.
5. After installation, apply the finish coats before the bathroom is used.

See it in your bathroom first

Order cork samples and check them against your vanity and tile in the room’s own light. If the product you sample is on sale, that price is held for 56 days after your sample order: checkout uses whichever is lower, today’s price or the price when you sampled.
