Can you have a wooden floor as a shower?

Wood flooring is a great choice for showers that lead out to a deck. With just a few houseplants, a wood-filled shower can be turned into a Zen-like retreat. Everything doesn’t have to be too much. Even a small room can look great with the right wood.

It is perfectly possible to have a wooden floor in a shower area, but there are a few important things to think about and challenges to face. Wood can look warm and inviting, but because it is porous and soaks up moisture, it can be damaged by water and rot if it isn’t taken care of properly.

For wood in a bathroom shower to stay straight and not warp or rot, it needs a waterproof finish. Even if it is done right, it may need to be resealed more than once to keep its structure for a long time.

Also, the type of wood is very important. Some trees, like teak or cedar, are naturally more resistant to water and can be used in wet places. But compared to other flooring options, these woods can be expensive.

How do you waterproof a wooden shower floor?

Can you waterproof wood for shower? Yes, waterproofing wood for the shower can be achieved by using sealers. They’re usually a clear/transparent finish that goes on the outside of the wood. Sealants such as polyurethane, varnish, and lacquer give excellent waterproofing and can be used for showers.

Waterproofing a wooden shower floor is crucial to protect it from water damage and ensure its longevity. Follow these steps to effectively waterproof your wooden shower floor:

Choose the right wood

Opt for water-resistant wood species like cedar, teak, or redwood. These woods naturally contain oils that help repel water and resist rot.

Proper installation

Ensure that the wooden floor is correctly installed with tight joints and gaps sealed to prevent water from seeping through.

Seal the wood

Apply a high-quality wood sealer or waterproofing agent designed for outdoor use. Coat the entire surface of the wooden floor, including all sides and edges, to create a protective barrier.

Use waterproof caulk

Seal all seams and joints with a waterproof caulk or silicone sealant. This will prevent water from seeping into the cracks and causing damage.

Apply a waterproof membrane

Consider adding a waterproofing membrane over the wooden surface. There are various products available, such as liquid-applied or sheet membranes, which provide an extra layer of protection against water intrusion.

Regular maintenance

Even with proper waterproofing, it’s essential to perform regular maintenance. Periodically check for any signs of wear, reapply sealant as needed, and address any issues promptly to prevent water damage.

By following these steps and using appropriate products, you can effectively waterproof your wooden shower floor, making it durable, safe, and resistant to water-related issues.

How do you stop wood from absorbing water?

There are two basic product categories for waterproofing: stains and sealants. Stains are used on wood to enhance color and make them weather resistant. Sealants protect concrete and wood from moisture but do not stop water movement through the concrete from the outside. For masonry, the sealants are the go-to product.

There are a variety of methods and treatments that may be used to make wood more water-resistant and protect it from water damage. Here are some tried and true techniques:

Sealants and coatings

Applying water-resistant sealants, varnishes, or paint to the surface of the wood creates a protective barrier that hinders water penetration. These sealants help repel moisture and prevent it from seeping into the wood fibers.

Pressure treatment

Pressure-treated wood involves subjecting the wood to chemicals under high pressure. This process impregnates the wood with preservatives, making it resistant to rot, decay, and water absorption.

Oil-based finishes

Using oil-based finishes like linseed oil or tung oil can provide a waterproof layer that prevents water from soaking into the wood.


Applying wax to the wood’s surface can create a water-repellent coating, reducing water absorption.

Proper storage

Storing wood in a dry, well-ventilated area, away from direct contact with the ground and moisture sources, helps maintain its dry condition.


Regularly inspecting and maintaining wood structures, such as decks and fences, ensures any damaged or worn-out water-resistant treatments are repaired or replaced promptly.

By employing these methods, wood can be safeguarded against water absorption, extending its lifespan and maintaining its structural integrity in various applications, from outdoor furniture to construction materials.

Can you lay shower tray on floor boards?

If you’re putting your shower tray on wood flooring, make sure the floorboards are well-fixed and in good shape. Resin trays made of stone can be heavy. If they aren’t attached well, get thick grade wood and cut it to the size of the shower tray.

Most of the time, you shouldn’t put a shower tray right on the floors. Shower trays are made to be set up on a flat, stable surface so that water can drain properly and there aren’t any leaks or other problems. Floorboards are not a good base for shower trays because they may not provide enough support and may move over time, which could cause structural problems.

For a good installation, it is best to give the shower tray a strong base. This can be done with a mix of things, like cement boards or a wet room tray maker. Cement boards provide a stable, waterproof surface that can be put on top of the floorboards. This gives the shower tray a good place to sit.

Another popular choice is to use a shower tray raise kit. The raise kit has legs that can be adjusted to the right height and hold the tray securely, no matter what condition the floorboards are in. This method also makes plumbing and waste pipes easy to get to.
