anyone replaced their Thetford toilet with a 320 elongated Dometic toilet

[Jerryr]

When the 320 is mounted with a 11" distance wall to centerline of the flange bolts, it sits right at about 3/4" off the wall at the dam.

Thanks for that measurement. It’s going to be close in my 337RLS.

I just ordered one from Home Depot to be delivered to the store next week. HD offers 10% Veteran Discount and free shipping to the store. If it doesn’t fit HD will take it back at the store.

I want to install the 320 so I can install a bidet seat which won’t mount on my current toilet.

the Thetford toilet mounted in the 2022 solitude used a 10" setback (mounting bolt to the wall)

I want to install a 320 dometic with an elongated bowl and wondering if it will fit. The 320 calls for a 11" setback.

if anyone has done this or has a 320 on another trailer could you tell me the distance between the wall and the back of the toilet when mounted.

see the photo for a better explanation

I have done this update in my Reflection. I'm sure you could do it in a Solitude. I never posted a "how I did it" but a while back my toilet flange broke so I did one for that repair. You will find it helpful in replacing the toilet since part of the procedure for doing so is contained within that post. You can find it here: https://www.mygrandrv.com/forum/show...hlight=dometic

Take a look at your lower cabinet door height. On mine I had to cut the bottom of the cabinet door off (about 1/2") to clear the top of the bidet seat. The combination of the "tall" 320 and the bidet got tall enough to conflict.

Jim,

Thanks for the heads up On the Reflection 337RLS there doesn’t seem to be any cabinet that would cause interference. There are no doors on the linen cabinet and the sink cabinet is far away.

I actually did the bidet seat too. Maybe this will help. https://www.mygrandrv.com/forum/show...924#post300924

Your original bidet install posting got me started. Unfortunately the Brondell bidet can’t be bolted/installed on my current toilet due to the toilet design. That’s why I ordered the 320.

What toilet do you have?

Gotcha, mine has doors on the linen cabinet.

Thanks!

Looking at your bidet installation posting I see you have a Dometic 320.

I already did the plumbing modification and after that I realized the Brodell would not mount to my current toilet.

I’ll report back at the end of the week with pictures after I get the 320 toilet and show my finished install.

I installed this same model in another trailer. To adjust for additional needed space (depth) I turned the flange to utilize the corner. The toilet is at an angle now and while it's counter-intuitive, gave a great result. I replaced the seat on the 320 with a sturdier household seat.

I installed the 320 on my 390RKR. I was told the setback had the same issue but the only interference issue was with the lid up and the shower doors locked in the travel position. And the Brondell seat actually fits better the way the water knob is situated. I think you'll be quite happy with both the 320 and the Brondell bidet
