Introduction
Installing a curbless shower in your bathroom is an excellent way to increase accessibility and safety. Curbless showers eliminate the raised “curb” or lip found in traditional showers and create a smooth, level entry. This allows for easy access, especially for those with mobility challenges or using wheelchairs. In this week’s Bathroom of the Week, we’ll explore the benefits of curbless showers and provide tips for designing and installing one in your home.
What is a Curbless Shower?
A curbless shower has no raised curb or threshold at the shower entrance. Instead, the shower floor is flush and on the same level as the rest of the bathroom floor. This creates a seamless transition with no lips or edges to step over or trip on.
Curbless showers are often designed with a gentle slope so water still flows toward the drain, rather than spilling into the rest of the bathroom. But the elimination of the curb makes entry and exit safer and more accessible.
Benefits of a Curbless Shower
Easier Access: The lack of a curb allows for easy “roll-in” access for wheelchairs and walkers. It also reduces the risk of tripping for those with mobility challenges.
Improved Safety: Curbless showers greatly reduce the risk of slipping and falling, especially when transitioning in and out of the shower. The smooth, flush entryway helps prevent trips and injuries.
More Open Design: Without a curb getting in the way, curbless showers feel more open and spacious. They allow you to move freely without obstruction.
Stylish Aesthetic: Curbless showers have a clean, modern look compared to showers with bulky curbs. The streamlined design makes them an attractive option.
Increased Flexibility: Curbless showers work well for users of all ages and mobility levels. They allow for more flexibility in design to meet varying accessibility needs.
Design Considerations for Curbless Showers
If you’re interested in installing a curbless shower, keep these design tips in mind:
Proper Slope: The shower floor should have a mild slope of 1/4 inch per foot to allow for drainage while remaining low-profile. Avoid excessively sloped floors.
Large Shower Area: Curbless showers work best with a wider shower area to accommodate wheelchairs or walkers if needed. At least 36-inches x 60-inches is recommended.
Grab Bars: Install secure grab bars along the walls to assist with stability and balance when entering and exiting the shower.
Non-Slip Surfaces: Use textured shower floor tiles or mats to prevent slips and falls, especially when wet.
Proper Waterproofing: Waterproof shower walls and pan properly to prevent leaks affecting surrounding bathroom areas.
Comfortable Seating: Consider adding a fold-down seat or built-in bench for resting when needed.
Adjustable Shower Head: An adjustable or handheld shower head provides flexibility for users of different heights.
Low Threshold: If a small threshold is used, ensure it is no more than 1/4-inch high for easy rolling over.
How to Install a Curbless Shower
Installing a curbless shower takes careful planning and preparation but is a manageable project for many DIYers. Here are the basic steps:
1. Remove existing shower curb and enclosure: Remove old shower pan, walls, curb and plumbing fittings. Inspect subfloor for levelness and make repairs as needed.
2. Waterproof the shower pan: Line shower pan area with waterproof liner or membrane per manufacturer instructions. Slope gently toward drain.
3. Build shower floor: Pour self-leveling concrete or install pre-sloped shower pan system. Slope 1/4 inch per foot.
4. Install tile: Select non-slip tile and adhere to shower floor. Continue waterproof membrane up walls.
5. Install drainage: Make sure proper drainage is in place under the sloped shower floor.
6. Add shower walls and fixtures: Install backerboard, waterproofing, and tile on walls. Add desired shower head, handles, and accessories.
7. Seal and caulk: Seal all seams and edges with waterproof caulk.
8. Test shower pan: Fill pan and check for leaks before finishing surface installation.
Be sure to follow all building codes and work with experienced professionals if needed. Careful planning and execution will lead to a beautiful, accessible curbless shower.
FAQs about Curbless Showers
Are curbless showers required by code?
Curbless showers are not necessarily required by code, but they are recommended to meet accessibility standards like the ADA. Many building codes are now being updated to encourage curbless showers in new construction.
Do you need a door on a curbless shower?
A traditional swinging shower door can still be used with a curbless shower. Alternatively, a partial height divider or no door at all works well. The opening should be a minimum of 32 inches wide for wheelchair access.
What are the disadvantages to a curbless shower?
Curbless showers require careful planning and installation to ensure proper drainage and waterproofing. They also lose the containment provided by a standard shower curb, so the bathroom floor needs to be water-resistant.
How do you keep water in a curbless shower?
Proper drainage slope of 1/4 inch per foot and the use of small dams at thresholds help keep water inside curbless showers. Large shower areas also provide more “run-off” space before water reaches the bathroom floor.
Can you have porcelain tile in a curbless shower?
Yes, porcelain or ceramic tile can be used in curbless showers. Make sure tile has a Coefficient of Friction (COF) rating of at least 0.42 for slip resistance. Small tile with grout provides grip.
What is the optimal floor for a curbless shower?
Tile is the most popular curbless shower floor option for its durability and design options. Other choices are fiberglass or acrylic shower pans, resin floors, or stone resin composite floors that offer slip resistance.
Conclusion
Curbless showers provide an accessible, stylish, and safer option compared to traditional showers with high curbs and thresholds. They allow for easy entry and exit, particularly for those with mobility needs, thanks to the low-profile, no-lip design. With thoughtful planning and design considerations like proper drainage slope, grab bars, and slip-resistant surfaces, curbless showers can be installed successfully in most bathrooms. Considering a curbless shower is a great way to increase the accessibility, enjoyment, and safety of your bathroom for all.
