I am disabled and need to raise the base of my toiet from 17" seat height to 25"seat height to California residential code. How? I can not add to top of seat as I use a slide board so must be raised from base.

I want to pass California building residential code to raise my toilet height of the seat from 17" to 25" so it will be the height of my wheelchair so I can slide board across to the toilet--therefore the toilet raisers put on the top do not work. How can I add a platform or base at the bottom to get the height I need?

Build box from wall using 2x8's slightly larger then toilet base.

Rip 2x8's down to 6 3/4 inches. Extend toilet waste line. Use 2 layers 1/2 inch plywood or 1 layer plywood and 1 layer concrete board.

Finish with ceramic tile to match floor. Grout and install toilet.

This will give u 25 inches.

Good luck

Chuck

Change the toilet to one with a 25 inch seat height.

It will be the easiest option and cost the least.

I am not aware of any toilets with a 25" seat height. The raised seat option must be a b**ch to keep clean. If there are toilets with this kind of height I would be interested in knowing what models they are.

If no tall enough toilet is available, would a trapeze hanging from the ceiling work?
Hate to see you go to all the trouble and expense of raising a toilet.

I work with handicap people every day, This is what I do for a living, what is done is a change to the seat or a stand with a seat and arms is placed over or attached to the current toilet.

We deliver and set up these every day

What ADA / California Code are you exactly talking about ? We do lot of commercial plumbing in California but I am not aware of any requirement for 25" high toilets. Please, educate me...

Do as suggested above: build a box under the toilet to fit your needs. Also, Home Depot sells retrofit toilet seats. See if you can find one tall enough to fit your requirements.

Problem is OP says he has to use slide board, I can see the hesitation to use slide board on handicap seat. I say build the box.

No, now not the cheap seats that merely sit on top of a toilet, but a real professional seat, it sits on four legs and sits over the toilet seat. There is a insert that goes down toward the bowl.
They can have a drop arm ( they have arms to help you transfer) and one side can drop down for the slide board.

They make equipment just for what he wants to do, obviously he is not talking to a medical supply dealer.

Chuck,

Can you give the OP a link to this? Regards, Tom

This is one of the models I place weekly. They also make a models if a person is over 350 lbs. They come without arms ( the most popular) and with arms and with drop arms.
They are used with slide boards ( when done properly)
