Hey Tony,

Thanks for reaching out. Unfortunately, we don't carry the replacement lid by itself for the Dometic 310 series toilet.
The Dometic Wood Toilet Seat and Lid - Bone # DOM23FR that you were looking at is your best replacement option. It's a complete seat and lid assembly, and it's finished in bone to match your existing Dometic 310 toilet.

I haven't been able to find the lid sold separately, so replacing the complete seat and lid assembly is likely going to be the easiest solution.

What sort of camper do you have?

Hi Tony C, some time ago I replaced my toilet seat and was required to buy the whole seat assembly. It was easy to replace and im actually glad it wasn't sold separately. I hope this helps. Debbie

@DebbieD Thanks for your feedback. Glad the # DOM23FR was a simple install and is working well for you.

The replacement slow close lid bolted right in and has been working perfectly for several years. We live in our rig about 7 months a year. After buying I realized an equal seat can be bought at a home store for a lot less $. The bolt pattern is standardized. Just make sure you get the correct toilet bowl configuration. We own an Alliance Paradigm 310RL

@TomE Thanks for sharing. Seven months a year in the RV is a pretty good test, so it's great to hear the # DOM23FR has held up.

We have a therford toilet but therford does not make a wooden seat. So I bought the dometic oblong seat and it’s great. Just off centered my 1/4 of an inch, but hey it’s fine. The snap down covers for the bolts did not fit the therford setup so they were not used..

Wow, great improvement- the hinges are better constructed much more durable and the slow close really works. Highly recommend the upgrade

Hey Tony C, Take the plunge and buy it. I’ve spent endless amounts of time trying to find a seat that would replace this one from a big box store. The seat must accommodate the air gap at the rear of the bowl so you can put the cover back on for aesthetics. It’s a nice seat and it’s painful at that price point but good luck finding just the seat cover or the whole seat for that matter, anywhere else. I don’t think you can even get one directly from dometic. Ain’t that something? In the end, it is a nice seat
