Easily replace a damaged seat or cracked lid on your part-timer Dometic RV toilet with this bolt-on seat assembly. Wooden seat is sturdy and retains heat. Slow-close lid and seat quietly closes without slamming against the rim of the toilet bowl.

Michael: Hi there. I'm Michael with etrailer.com. Today we're going to take a quick look at the Dometic RV toilet seat. This is going to replace the toilet seat for your Dometic 310 and 311 series RV toilets.It does have the soft close feature to it, which we all know is important in our motor homes and RVs. They're not always the thickest walls, so if you're up in the middle of the night and you're done with your business, it will be nice to not have to wake everybody else up with a slamming lid.This is a wood construction seat and lid, so it is going to stay warmer in the winter. It's not going to be as cold when we go to sit down and it's going to be very easy to install.
We've got a two hole mount on the back here. You can see we've got all the hardware in there already. But basically you just drop those plastic screws through from the top side here into the two holes that are on your toilet and then go from underneath. Put those little nuts on there. And then on the top it's got these caps.
So, you cover up those holes. It gives it a nice finished look.This is a direct replacement for the 310 and 311 series. But just for the sake of peace of mind for some of you who may still be a little skeptical. Our overall dimensions: We're looking at right about 15 and a quarter of an inch long for our lid. And I lift this up.
Try and be careful because that soft close only works when it's attached. Our seat opening is right about 11 inches by about about eight inches there.And what I meant by be careful: So, if we don't have this portion installed, this lid will fall forward without the soft close functionality to it. So, you can smash your fingers like I did a few minutes ago. So, you want to be careful with that as you're installing this. Make sure that you have that bolted down in place before you allow the lid to come down, otherwise it will not close slowly or softly.This is made here in the USA and this is the white option.
There's also the exact same seat and lid combo but in tan. So, if you have a tan toilet, you can get that option as well. You can see the part numbers on the screen there for either option for you, depending on what your needs are.Overall, think this is going to be a great quality toilet. I really like that soft close feature there. The wood is going to make it feel more comfortable, more like your toilet seat at home. Plus you're not going to have to worry about that material getting cold in the winter time, so it's going to be more comfortable to use that way. Overall, I think it's a nice quality toilet. It's going to do the job that you needed to do and do it well. That's going to complete our look at the Dometic RV toilet seat. Thanks for watching.
Excellent product, timely shipping, easy installation. All is Well!
Unlike Amazon, etrailer gets it right. I order this originally from amazon but it was missing parts and had to return it. Frustrated I searched online and found it at etrailer. Shipping is just as fast as amazon and the item was correct and brand new. Thanks etrailer for caring about your products and customers.
Fit and finish is very good. Has all hardware for installation.
Fast shipping!
Beautifully crafted toilet seat. Fast delivery, well packaged
It’s an easy install and great upgrade

Still Great after One Year!
Perfect replacement
outstanding value...replaced my plastic lid setup with the wood replacement seat and it is a thousand times better. easy to install and the soft close feature is a plus
This was perfect! I dont understand why Dometic even makes the lousy plastic kind. Sturdy and both lid and seat close very slowly.
Let me start by saying that I did not fully research my toilet model and I have a 500 instead of a 310. That being said the part of the hinge that broke was the bracket attached to the seat itself so I was able to use the bracket that attaches to the toilet and just swap out the seat, lid and backers attached to those and everything works perfectly. Great quality product.
This seat is very sturdy and was an easy install in just a few minutes. The wooden design makes it easy to keep clean.
Fast shipping, product is exactly what I ordered. Customer service is excellent.
Works great. Love the slow close.
The product is fine, your promised delivery dates are terrible, delays, delays delays, never again will I purchase from etrailer, I can get the product elsewhere and when I need it, not when you hold it in your plant and then decide to ship it. On the UPS site it shows "Label created" but still at your dist. center. More lies as I tried to cancel it.
Same ole story, Every time I place an order its delayed and never arrives on time. Never again
Seat fit perfectly. Great to not have the lid slam in the middle of the night.
Great product upgrade. Was on back order but came within reasonable timeframe. Josh followed up and kept us posted.
YOUR SERVICE IS ALWAYS OUTSTANDING !
Easy install, much nicer than the original. Delivered three days later than promised date when I ordered.
Works well; a definite upgrade from the stock plastic seat.
Placed order by phone. Rep took his time with me to make sure I was receiving the correct model. Easy installation. etrailer has not let me down whenever I needed to order parts for my RV.
Easy installation. Nice to not slide around on the oem plastic seat.
A much better seat at a reasonable price thank you
A perfect fit for our 310 toilet!
Slow close worked like it was supposed to.

Glad we could get you back on your throne, John! : P Do you know which 310 toilet you installed this on? It fits a few of them.
