Hey Gang,

I have a simple one (at least from a replacement perspective). One of the hinges broke on my toilet seat. The toilet being a Sealand Magnum Opus, as far as I can tell.

Not super easy to find the correct hinges. Would like to replace the seat/lid, if not too costly.

Many RV toilets for class A's are 'near' the same size as regular home style. Have you measured your's to find out?

I just replaced my Dometic 510 and they pointed out that the toilet seat was a standard size available for any domestic toilet. I have a '02 Journey.

A new toilet seat will come with the hinges.

I've replaced both of my toilets seats for the same reason.

Bought them at Walmart. I was surprised at how many different toilets seats they stock.

I added some toilet seat bumpers to the bottom of the seat so it fit OK.

Who needs a toilet seat? Remove it and with the weight saved your gas mileage will increase. Plus you will spend less time in the bathroom

I dont think you will find one at HD or Lowes. You will have to get from RV or Marine dealer. I found the best price from a marine dealer in Washington state about 110.00 is the best I could find 09 harley gave a nice answer to be a senior member

BigJim8499 nailed it. We got our replacement from them, as well. The toilet seats are about the same size as residential, but the spacing between the attachment holes is a lot different.

Thanks All,

The spacing b/w the bolts is definitely wider than a normal residential lid/seat.

I found these hinges that look like they might work: https://www.marinesan.com/ProductDet...xoCdoIQAvD_BwE

I guess I'll reach out to the vendor to make sure before buying.

I don't see any point in paying over $100 for a lid/seat combo if I can just replace the hinge.

Good idea 09 harley. Could build some leg muscles that way too!

It's very common for the toilet seat hinges to break. Dometic now owns Sealand and has discontinued the Opus toilet. However, I called Dometic customer service (800-544-4881) and they gave me a part number (385311006 for one in "bone" color). This is actually for a newer toilet (model 4310) that uses the same design seat assembly.

You need your model number (ours is a model 3010) and color when you call.
I then found the new toilet seat for around $70 online.

A side note. An experienced RV tech told me to take a plastic bag and place it over the Sealand circuit board to protect it from moisture. These circuit boards are no longer available.

Nice tip!
There is really nothing in that space where the board is mounted. It is open to the air. But I suppose the proximity to the water bowl and the humidity in the bathroom could let condensation accumulate on the board.

Is the suggestion to try to fully seal the board in the plastic bag other than wires coming out) or maybe install bag with bottom facing down and left open to let air in and moisture escape?

What's you take on this?

I slit the plastic bag down one side and covered the board with it.

Hi vito.a !

I ended up ordering this replacement lid/seat/hinges all together and in te bone color I have: https://www.marinesan.com/Seat-M-O-C...-385311006.htm

I noticed the part number seems to match up to what you provided, so I am even more confident that it will work. BTW, they are super helpful at that company. Had a great experience ordering from them.

Thanks for the plastic bag idea! I hope mine lasts a long time. As an aside, the gentleman who sold me the coach told me I needed to throw water down the back of the toilet (he was older and I am sure he was thinking about another RV he had previously owned). When I saw the blinking lights, I knew enough not to "prime" a circuit board with water. LOL!

vito.a · 07-12-2019, 10:26 PM

That's funny. Wow, you found a great price on the toilet seat.
It was a little tricky installing as the bottom nut is recessed way up inside the porcelain.
I used a set of needle nose pliers to hold the nut up in there and then screwed the bolt into it from above.

I removed both these toilets from my coach and just replaced the one with a standard RV gravity flush.

I kept both printed boards from the toilets and they are available for cost of shipping to you. I think they retail for around $1000 each? So free is a good price.
