Replacement. A common mistake is replacing a standard rim toilet with an elongated bowl toilet. After the toilet is replaced the door that opens at a right angle to the toilet will not close. Always measure the space in front of the toilet to avoid any obstructions. Another issue is replacing a standard close-couple toilet with a low-profile one-piece toilet. Be aware that the shut-off valve most likely will need to be lowered. This could require access to the wall behind or beside the toilet. Consider the wall material and difficulty of access.
Finally, as our clients age, it will be important to consider blocking for grab bars in the toilet area. Toilet compartments will need to be enlarged for wheelchairs, walkers and caregivers aiding their patients. Plus, 36-in. wide doors will become commonplace as well.
