Dometic Master Flush 8700 macerator toilet seat replacement

Lots of talk and discussions I found when I searched, but no good solutions for replacing the toilet seat on the Dometic Master Flush 8700 macerator toilet.

However I found a solution. Apparently the seat on this is what is called "D shaped". And on Amazon I found a pretty cheap, plastic, soft close and easy to remove/clean replacement seat.

Its made by Sadalak (no, never heard of them) it costs $39 bucks.

[Moderator Edit]

I am very happy with this purchase!

Great post.....many of us Newmar owners have been looking for a slow close seat for the 8700 Dometic, the standard toilet in many Newmar units. The problem has always been the hole pattern. Too bad they didn't make those adjusters white like the rest of the seat. I ordered one to see how I like the quality and will order a second one if I like it.

The cover caps are white.

Itíll be interesting to hear the results here. Looking at the seat and cover, it would appear that the lid / cover has a significant lip. I would think it could be a sharp pain in the back maybe.

Its not a problem, the cover lays back quite a bit. Its not a lazybowl reclining toilet..

Order came in and it is going back.

The seat was a bit too narrow and too long. That is the bowl porcelain stuck out by about a half inch on sides and front of seat was hanging over the front of the bowl by an inch.

Could have dealt with those but the darn thing would not open.

I was worried about dropping something in the bowl so taped a trash bag over the top. That helped. But I did drop one of the wing nuts which vanished. It might show up after hitting a few bumps.

No offense to the OP.....I was excited about his find, but mine arrived and there were too many differences for ME personally to use it. I sent it back. I really like the adjustable mount; I wish it would work with any toilet.

It just so happens that we are remodeling our master bath in our house. I removed an old Bemis slow close seat and discovered that the hinges look almost identical to the Dometic seat, with a similar or identical screw pattern.

Even though those seats are about $35.00 at Home Depot, if you can just swap the hinges, it would be worth it. Taking my measurements to HD in the next few days and see if they can be swapped.

Dometic made the seat difficult to find an exact match in slow close, the material, shape, color and fitment are just too tough to match.

Sorry for those not happy with it. Keep in mind D shaped seats are common on bidets so looking for others may help you find something that works for you. Just make sure they are adjustable to the width of the holes for mounting.
