Bidet on dometic 300

[Peacester]

Wife really wants a bidet. Before I had realized the toilet model I had ordered a clean camper bidet. It almost looks like it would fit with some modification to the toilet. Any one else done this? Is there a toilet I can get that will fit the bidet that won’t cost me over $200?

Moved thread from the Modifications and Updates section to the Plumbing, Water Systems and Fixtures sub-forum since the OP's questions are specific to that sub-forum.

I may be wrong but I believe the dometic 300 is the model with a lot of issue, if that is the case I would replace it either way.

I have a Domestic 300, or a 320, and installed an Amazon bought bidet with auto heating and changeable spray patterns and such. I will never go back!

i don't know about the clean camper bidet, but if you've got a Dometic 300 than it's a ceramic toilet and modifying the toilet itself will result in shattering and other bad things.

Due to known issues and our experience with the Dometic 300 (leaks and stinks), I removed it and replaced it with a Dometic 310.

Then I added the toilet seat bidet. The heated seat and warm water are sooooooo nice in the Fall, Winter, and Spring.

The Dometic 300 is all plastic(polypropylene) and prone to many problems( urine odor most common). The 310 and 320 are ceramic bowls. I would hesitate to modify or add accessories to the 300 and have to replace it in a very short time. Get the 310 which fits the same footprint and go from there or get the 320 with the elongated bowl if you have the room.

Just think about it. No more T-paper in the black tank. We purchased our first bidet during the T- paper shortage during COVID. We liked it so much, that we purchased another one for the TT.

Now the 2 AM nature call, even when snowing and freezing outside, is no longer a dreaded trip. Ahhh, warm seat, warm water, warm air.

Dometic 300 and bidet

I have the 300 series Dometic and it sounds like I should replace it with a 310 or 320. If I do, will an ordinary household bidet fit? What bidets have folks used with the 310 or 320?

I'm a boat mechanic, assuming the swap from 300 to 310/320 is pretty straightforward?

Thanks.

If you have the front to back space, go with the 320, the elongated oval bowl is so much easier to find accessories for. They all should bolt up with the same pattern. I just installed a Toto Washlet C5 bidet on my 320, and it is luxury personified.

They make RV specific Bidets which are all non-electric as far as I could find, and they're all pretty basic... I had a cheap one that decided to start leaking on my floor last week, so I upgraded as much as I could!

Just know that you're gonna have to do some fancy plumbing for any residential bidet, and if you want fancy stuff like drying, heated seat, UV sterilization, Bowl deodorization, and water heating, your also going to need an outlet nearby... Residential Bidets take water from the feed going to the toilets water tank, which uses a 7/8 Ball Cock thread pattern, whereas our RV toilets use 1/2 Iron Pipe (MIP and FIP) thread fittings.

I had a lot of PEX coming out of the floor to work with, so I installed a 1/2" sharkbite to 1/2" MIP shutoff valve (so I don't have to run back and forth to my distribution block), a 1/2" tee, (FIP, MIP, MIP) one male leg with a 1/2 FIP to 1/2 FIP braided hose to the toilet's valve, with the other leg of the tee having a 1/2" NPT Toto adapter (Toto Bidet's use a weird proprietary water connection of course) connected to the Bidet itself. It's complicated, but minimizes strain on everything, and the Washlet bidet is worth every penny.

Thanks, that's very helpful, and thanks for the plumbing detail as well. I'm not sure I have the room for the 320, but will check before ordering the 310 or 320. I travel to Taiwan for business, which is where I was first introduced to the Toto, pretty much every hotel there has one, and it is brilliant. The first time my wife accompanied me on a trip, she agreed, and in a few months we had one at home. Everyone should have one.

I took a similar approach, and thanks for the plumbing inspiration. On the advice of the forum I changed the commode to a 310, and yes it clearly a much nicer product, and accommodates the bidet. I then installed the Neo 185. I also got creative with plumbing fittings, but all standard NPT and compression fitting parts available at the hardware store. I also installed an inline shut off valve. I still need to get a cover plate to dress up the penetration in the bulkhead for the hose. It all went well, and thanks to all for the advice. Critique welcomed.
