If a walk-in shower is not properly designed or if the water pressure is too high, water may splash out. There are, however, ways to reduce water splash and keep your bathroom dry. 1) Installing a shower pan or threshold at the shower's entrance can help contain water within the shower area. This is especially important if your shower floor is the same as the bathroom floor. 2) Another option is to install a sloped ceiling or a showerhead that directs water away from the entrance and toward the back of the shower. This can reduce the amount of water that splashes out of the shower. 3) Consider installing a shower curtain or a glass partition to help keep water contained within the shower area. This, however, will not work for a walk-in shower with no doors
