Why Build a Shower Bench?

A shower bench is more than just convenience. It provides comfort, safety, and a sense of luxury in your bathroom. For wood enthusiasts, crafting a wooden shower bench allows you to combine creativity with functionality. Whether you are aiming for a minimalist design, a rustic spa feel, or a modern statement piece, building your own bench ensures it fits perfectly in your space.

Creating a shower bench yourself also allows you to choose the best wood, finish, and joinery methods, ensuring it withstands moisture and daily use. This guide provides a comprehensive walkthrough from initial planning to finishing touches. By the end, you will know exactly how to build a shower bench that is stylish, practical, and durable.

Planning Your Wooden Shower Bench

Proper planning is the foundation for any successful woodworking project. Consider the following factors before starting your build:

Design Considerations

  • Dimensions: Standard bench height is 17–19 inches, with a width of 12–16 inches. Adjust as needed for your shower. Always measure your shower space carefully to ensure the bench fits comfortably without obstructing movement.
  • Weight Capacity: Choose strong hardwood capable of supporting at least 250 lbs. Reinforce the joints and supports to handle additional weight safely over time.
  • Style and Shape: Options include slatted, solid, folding, or corner benches depending on your bathroom layout. Consider your bathroom design and personal preferences when selecting the style to complement your decor.
  • Drainage: Ensure proper spacing between slats to prevent water pooling. Proper drainage helps prevent mold growth and prolongs the life of your wooden shower bench.

Wood Selection for Wet Environments

  • Teak: Naturally water-resistant, highly durable, and ideal for shower use. Its natural oils help prevent cracking, warping, and decay even in constantly wet environments.
  • Cedar: Lightweight, aromatic, and resistant to rot. Cedar also repels insects and adds a pleasant natural scent to your bathroom space.
  • Ipe or Mahogany: Very durable but may require professional tools to handle. These hardwoods provide exceptional longevity and a luxurious appearance, making them worth the extra effort for premium benches.

Avoid softwoods like pine or untreated oak as they absorb water and can warp or rot over time.

Essential Tools for the Project

  • Saw (table saw or handsaw)
  • Drill with appropriate bits
  • Sandpaper (120–220 grit)
  • Measuring tape and carpenter’s square
  • Clamps for holding joints during assembly
  • Waterproof wood glue and protective finish

Expert Tip: Always double-check your measurements before cutting. Accurate cuts ensure a stable and balanced bench.

Step by Step Guide 

Building a wooden shower bench is manageable if you follow the steps carefully.

1: Measure and Cut the Wood

  • Measure the shower space where the bench will sit. Take into account any obstacles, such as shower doors or faucets, to ensure a proper fit.
  • Cut seat, legs, and support pieces to exact dimensions. Using precise cuts will help the bench sit level and provide maximum stability.
  • Double-check all measurements before cutting to avoid errors. Mark each piece clearly and re-measure to prevent mistakes that could waste wood or affect assembly.

2: Assemble the Frame

  • Attach the legs to the support beams using waterproof wood glue and screws. Ensure the glue is evenly applied and screws are fully tightened to create a strong, lasting bond.
  • Clamp the joints to ensure they are tight and square. Double-check alignment with a carpenter’s square to prevent any wobbling in the finished bench.
  • For extra stability, include crossbars or diagonal supports. These reinforcements distribute weight evenly and increase the overall durability of the bench.

3: Attach the Seat

  • Slatted seats should have small gaps (about 1/8 inch) for water drainage. This allows water to flow through freely, preventing pooling and reducing the risk of mold or mildew.
  • Secure the seat to the frame using screws and glue. Make sure each screw is countersunk slightly to avoid protruding edges that could catch on towels or skin.
  • Sand all edges smooth to prevent splinters. Take extra care on corners and slat ends to ensure the bench is safe and comfortable to sit on.

4: Finishing the Bench

  • Apply a waterproof sealant or oil finish, such as teak oil. Make sure to cover all surfaces, including undersides and edges, to fully protect the wood from moisture.
  • Allow the finish to dry completely before use. Drying times may vary depending on the product, so follow manufacturer instructions for best results.
  • Optionally, add non-slip pads under the legs for safety. These pads help prevent the bench from sliding on wet bathroom floors and provide additional stability.

5: Inspect for Safety

  • Test the bench for stability and weight capacity before use. Sit or gently apply weight gradually to check that the bench can safely support its intended load.
  • Ensure all screws are tight and surfaces are smooth. Recheck each joint and screw periodically, especially after initial use, to maintain long-term safety.
  • Make any adjustments needed for balance or drainage. Small tweaks to leg height or slat spacing can improve stability and ensure water drains properly.

Maintenance Tips

To prolong the life of your shower bench, regular maintenance is essential:

  • Clean Regularly: Use mild soap and water; avoid harsh chemicals. Regular cleaning removes soap scum and mineral deposits, keeping the bench hygienic and looking new.
  • Reapply Finish Annually: Maintain water resistance by applying oil or sealant yearly. Re-coating the wood helps prevent cracking, warping, and water damage over time.
  • Inspect Joints: Check screws and glue for loosening; tighten if necessary. Early detection of loose joints prevents accidents and ensures the bench remains stable.
  • Ensure Drainage: Prevent standing water by ensuring proper slat spacing. Good drainage reduces the risk of mold and prolongs the lifespan of your wooden shower bench.

Pro Tip: Removable or foldable designs are ideal for small bathrooms, allowing you to save space while keeping the bench functional.

Real-World Case Studies

  • Jane, a DIY enthusiast, built a teak shower bench for her master bathroom. She used reclaimed teak wood and a slatted design for water drainage. After two years, the bench remained sturdy, resistant to mold, and added a touch of luxury to her bathroom.
  • Mark created a corner folding cedar shower bench for his small bathroom. By incorporating folding hinges and a support bracket, he was able to build a shower bench that maximized space while keeping a spa-like atmosphere. His bench has now been in use for over three years without warping or deterioration.

These examples show that proper planning, wood selection, and construction techniques are essential for long-lasting performance.

Tips from Experts

  • Always select wood with natural water resistance. Teak, cedar, and ipe are excellent choices when you build a shower bench. Choosing naturally water-resistant wood ensures the bench remains durable and resistant to rot in a wet environment.
  • Keep slat gaps uniform to ensure proper drainage and prevent water pooling. Even spacing allows water to flow freely, reducing the risk of mold and prolonging the bench’s lifespan.
  • Sand all edges and corners thoroughly to avoid splinters. Smooth edges not only improve safety but also make the bench more comfortable to sit on.
  • Use high-quality screws and waterproof glue to enhance stability. Durable fasteners prevent joints from loosening over time and ensure the bench can safely support weight.
  • Regularly inspect and maintain the finish to prolong the bench’s lifespan. Periodic maintenance keeps the wood protected, maintaining both its appearance and structural integrity.

Conclusion

Building a wooden shower bench is a rewarding DIY project that combines aesthetics, functionality, and personal craftsmanship. By carefully choosing the right wood, following precise measurements, and applying proper finishing techniques, you can build a shower bench that is both durable and visually appealing.

Whether you opt for a slatted or solid design, a foldable or fixed model, building your own bench ensures a custom fit tailored to your bathroom space. Start your project today and enjoy the comfort, safety, and charm of a handmade shower bench.
