Are most toilets pretty much interchangeable

Good Luck

Uh, be careful, mine wasn't so easy. Make sure you measure carefully to see if it fits. I changed out my original and put in a Dometic 310. We are very happy with it but I had to modify the back of the lid and carve a teeny bit into to the back wall to get it to fit. Works like a charm and the porcelain bowl is very nice. This will be a great improvement for you. Good Luck.

If you have a door that swings over or close to the front of your toilet, pay special attention to the dimensions of the new one. Last time I replaced mine the new one only cleared by 1/4". That was a close one!

^^^ my Dometic 320 was the same but my mounting bolts are 10 1/2 inches from the wall so the 320 was a perfect fit. Craig

in general almost identical. There are a few that are longer in the back than others and that can pose a clearance issue in tight quarters.

ours is now a dometic 320 and it was slightly longer in the back than the previous (310?) it fit but very little rear clearance compared to the original.

I put in a domestic 320 a few years ago and it’s been flawless.. Chair height, elongated china bowl and a good quality seat. Craig

We installed a Thetford Aqua-Magic Style Plus toilet in our first Class A in 2008 to replace a damaged toilet. In 2013 we moved the toilet to another new to us Class A that we still have and are still enjoying the Style Plus. The porcelain bowl is easy to clean and the residential seat is a bonus. The only repairs we've made in all that time is replacing a couple of ball seals and a spring.

We went from the Thetford Aqua Magic Style II to a Dometic 320. Dropped right in and didn't have to change a thing.

For RVs this mostly applies. I've never seen exceptions
Comments on house Toilets later.

There are 2 by 3 by 3 toilets for RV's plus one more

Two: Short or tall. Tall ones are designed to mount to the floor. Short's to a Riser there are very good reasons for this.

Where is the flush pedal (1: left 2: Center 3: Right)

and 1: Round 2: Short oval 3 Full size oval

The additional type is gravity dump or macerator type but clearly you can't swap those.

On the first: Must have same height

On the second. 1 and 3 might be a problem as the water vave is on the same side as the pedal.. 2 The water valve is in teh back and a length of flexible water line is all you need to fix it (how I did it)

and on 3: Depends on the size of .... Your seat.. I like the full size oval


Finally some need "Special" seats. Many take seats you can find at your local Plumbing supply place.. Lowes. Home Depot, Menards, Wal*Mart, Joe's hardware.

Mountings are usually universal and the water connection is as well

HOUSE comments: There is a measurement.. Toilet outlet to wall, that varies from Toilet to Toilet... So sometimes you need to measure that to be sure. Oh and I like TOTO toilets.. They fulsh better.

if your handy pull the thing get a repair kit first. on a nice warm day rebuild it. not real hard .

We had a Thetford. Once while flushing it the pedal slipped off my foot and broke. I figured that parts would not be available and ordered a new one, then found parts locally. The new one came and it was a couple years before we found someone who needed it.
