According to the Center of Disease Control, around 235,000 non-fatal injuries are suffered in the bathroom per year within the USA with over 80% directly caused by falling. This is often due to the slippery surface of the room's waterproof flooring. Thus remodeling the bathroom floor for greater safety and accessibility should be a priority when it comes to preparing a household for aging in place, especially as 80% of all falls by those aged 65+ also occur in the bathroom (with an estimate of around 1/3rd of the senior population potentially suffering a fall during the year).
Flooring can be measured with a dynamic coefficient of friction whereby the higher the number, the better the slip resistance. For the bathroom, a coefficient of 0.42 or higher will be needed. While the ceramic tile industry has adopted these friction ratings for safety reasons, other materials are optimally recommended for floor use in the bathroom.
Most pre-installed bathroom floors are tiled and are usually made from ceramic (or potentially porcelain, glass, or marble). This is done as an inexpensive & easy-to-maintain way to create a waterproof surface. However, these types of flooring tend to be very slippery when wet which poses a great falling risk when the bath or shower is in use. In addition tiled flooring can create another tripping hazard if its tiles or connecting grout are uneven.
It's generally recommended that ceramic and other tiling be replaced with textured waterproof sheet vinyl or sheet rubber which will not become slippery when wet. While rubber flooring is generally viewed as the safest choice due to its greater cushioning for shock absorbance during falls, it's also the more pricey option with non-slip vinyl being a good inexpensive alternative. In addition, sheet vinyl flooring comes in a wider array of decorative patterns such as those that mimic hardwood, marble, or ceramic tiling.
Sheeting that has been cut to the exact dimensions, size, and shape of the bathroom is recommended over normal tiling as the solid surface creates a more waterproof environment without the potential for moisture to collect at the edges of the tiles (which then can seep into the insulation beneath). The lack of grouting also adds to a more even surface with less potential lips, corners, or edges to trip over.
The bathroom flooring, both within its main section as well as in its bathing or shower area, should have a textured surface in order to help prevent slippage. Generally it's best to have a non-skid surface directly molded into the floor and bottom of the bath & shower so that extraneous mats and rugs will not be needed (as the edges of the mats as well as the sudden change in surface has the potential of posing its own tripping hazard).
If the floor of the bathroom is not naturally textured, then a slip resistant treatment is highly recommended. This would include the addition of gritty no-slip paint or other coatings with a friction coefficient of at least 0.42 or higher as well as adhering heavy duty anti-slip strips directly to the floor.
Additional Flooring Options
If the tub or shower does not have a non-skid textured surface, then non-skid rubber mats, waterproof treads, or shower strips made specifically for bathing areas will need to be added to the floor surface. Care must be taken that the mats or strips are tightly bonded directly to the surface so that they don't pull free or bunch up, which would then pose their own tripping hazard.
If the general floor area of the bathroom is not comprised of waterproof textured vinyl or rubber, then it may be necessary to have non-skid, low threshold bathmats in potential slippery sections where moisture might collect on the floor. This would include the entrance & exit of the tub or shower as well as the front of the sink.
These bath mats should be low pile and on the thinner side with preferably sloped edges to help mitigate the potential of tripping over the mat threshold due to the change in surface height. The mats should be slip resistant with rubber backing that fastens directly to the floor using anti-slip rug tape (preferably the type rated for use in the bathroom or other moist areas) to make certain that the rug will not easily bunch up or slide around during use.
