Ideal for Part-Time RVers

When you're taking your RV on the road for weeks at a time, you'll want to make sure your toilet can handle that long a journey. This toilet is built for part-time RVers who use their RV more frequently than just on the weekends. It's just as tall as a standard residential toilet, so it's easy to sit down on and get up from. The ceramic bowl is more durable and easier to clean than a plastic bowl. And the lid closes slowly, so it won't loudly slam against the rim. This toilet provides the durability and ease of use needed for your long RV adventures.


Measure to Fit

RV toilet rough in measurement

There's one measurement you should double check to see if this toilet will easily fit into your bathroom. The rough-in measurement is the minimum distance you'll need from the wall to the center of the flange on which the toilet will sit. To measure this distance without uninstalling your current toilet, the mounting bolts on the side will typically tell you where the center of the flange is. You may want to triple check if your toilet has an offset flange or 4-bolt mounting style.


The Dometic 310 Series RV toilet has a rough-in measurement of 10". If your rough-in measurement is less than 10", select a toilet model with a lower requirement or consider alterations to make it fit. Keep in mind the overall dimensions of the toilet, and measure for yourself to pick the best model for an easy DIY upgrade.

This toilet is so much studier than the cheaply made 300 series one that came in my 2019 Springdale travel trailer that leak between seals and smelled




by:

I just got the Dometic 310 installed and have not had an opportunity to try it out under real world conditions. It feels a lot more stable than the 300 model and does not have all of the creaks and groans of the 300 model. It arrived in a timely manner and installed easily. It is installed in a MicroLite 25BRDS.




by:

I ordered my Domestic 310 as a replacement for my substandard Domestic 300. The folks at etrailer were great! They answered all my questions and my new toilet arrived on time and undamaged. The installation is pretty straightforward and the new toilet works as advertised!




by:

The toilet I'd good. It mainly does what it's supposed to do. It doesn't hold water in the bowl, like it should and when you push the peddle down slightly to add water to the bowl, it breaks the seal and let's the water escape. Also, shipping was horribly slow.


Comments
I reached out to the manufacturer who did have some advice in regard to the water remaining in the toilet bowl. They advise that when this happens 99 percent of the time the toilet ball seal needs a deep clean or rejuvenated. The first step would be to make sure that the ball valve is secure as it can become displaced if the toilet brush knocks the flush ball valve out of its pivot place .To assure the ball valve is in place compress pedal halfway and grab the ball valve. It should not be able to move, except for forward and backward. If there is play you will need to move the ball valve around until it finds its way back into its pivot hole. To help rejuvenate the seal, it needs to be removed. To remove the ball seal partially compress the foot pedal so the ball valve retracts. Reach in and grab the ball seal and remove. To clean it, take a small brush and clean around the area of the flush ball and ball seal. You can get debristoilet paper and or calcium build up that will keep the flush ball from sealing properly. To replace the ball seal, remember to keep the ball valve closed when reinstalling. Squeeze the seal and push it in place. With the ball seal back in place, pour several cups of very hot water into the toilet and leave it sit. This will help to rejuvenate the seal. Once water cools resume use as normal.

Nice looking toilet,will install next week.I am waiting for sprayer




by:

This would have been 5 stars except when the product came in it was damaged I sent pictures immediately and they said they would send another right out. 5 days later they asked me if they could just send the part that was broken I said so the only problem I have is why did they wait 5 days when they knew what the problem was,so then l had to wait another 4 days to get the item.


Comments
I apologize for the inconvenience. The customer service department and reship department are separate so there was a communication error there.

Installation was very simple. Haven’t used the toilet yet, but it appears to be a huge upgrade over the plastic unit that came with the trailer.

by:

Arrived in great shape on time. Just installed it every thing looks good, just need an opportunity to use it!




by:

The install went very smooth, in the toilet looks great. But the toilet is a little tall. If I had to order another one I would have went with the shorter one like the one we had. 2" is a big increase! I am 5'7" and my husband is 5'9".

  • Are Any Parts Not Included With The New Dometic Part-Timer RV Toilet Needed For Installation?
    The Dometic Part-Timer RV Toilet - Standard Height - Round Bowl - Slow Close Lid - White Ceramic # DOM57FR comes with the new mounting hardware and new seal so there is nothing else required for installation. Your current water line should connect right up as long as it is in good working condition.

  • Will the Dometic Part-Timer RV Toilet 310 Series Replace a 300 Series
    The Dometic Part-Timer RV Toilet (310 Series) part # DOM57FR should be a direct replacement for a 300 Series Dometic Toilet. I took a look at some reviews and many have done this stating it was pretty much plug-in-play with only slight modifications. I don't have any dimensions on the water inlet height unfortunately though.

  • Will The Dometic 310 Part Timer Toilet Work For Long Term Use.
    The Dometic 310 Part-Timer RV Toilet - Standard Height - Round Bowl - Slow Close Lid - White Ceramic # DOM57FR was designed to be able to be used year round, meaning it has some of the same features that a normal "house" toilet will have. Like using ceramic for the bowl instead of plastic and making it taller than a standard RV toilet. A part time RV'r is someone who uses their RV more than the ordinary user for example boondocking or traveling for weeks at a time or using the RV 3 days...

  • Dometic 910 Part-Timer RV Toilet Replacement
    Yes, the Dometic Part-Timer RV Toilet # DOM97FR (NLA) is the same as the Dometic 310 series toilets. Unfortunately, this toilet has been discontinued. Instead, you can use the Dometic 310 Part-Timer RV Toilet # DOM57FR. This is the same toilet as # DOM97FR, but # DOM57F doesn't have a hand sprayer.

What I recommend is the Dometic 310: - Dometic 310 Part-Timer RV Toilet # DOM57FR I like the # DOM57FR due to its slow close lid and efficiency as it uses just 1 pint of water per flush.

  • Can a Slow Close Lid Be Added To a Thetford RV Toilets
    I do have an option for you but we don't have any parts that allow you to upgrade to a slow-close lid feature on a toilet.

They are offered in standard height part # DOM57FR and low profile part # DOM67FR.

  • Comparing Dometic 310 Toilets 302310093 and 302310081
    The biggest difference between the Dometic 310 part 302310093 you've currently got and the Dometic Part-Timer # DOM57FR is that the Part-Timer comes with an all wood, slow-close seat where your existing model is the retail model that comes with the plastic seat. The other difference is the color, since the # DOM57FR is white where your old toilet is considered a "bone" color.

    The main difference between the Dometic 310 Part-Timer RV Toilet # DOM57FR and the Dometic 311 Part-Timer RV Toilet # DOM67FR is that the 310 is standard height (20" tall) and the 311 is a low profile (15-1/2" tall).

  • Replacement Toilet Recommendation For A SeaLand Model 210
    For your SeaLand Model 210, I recommend the Dometic 310 Part-Timer RV Toilet # DOM57FR as a replacement over the Dometic 320 Full-Timer RV Toilet # DOM87FR that you mention. The Dometic 310 Part-Timer RV Toilet # DOM57FR features a slow-close lid, a sturdy ceramic design, and a 2 bolt installation that will fit most floor flanges. Additionally, the 310 Part-Timer # DOM57FR has a rough-in measurement of 10" compared to # DOM87FR which has a rough-in measurement of 11".

Both have a ceramic bowl and constructed to a standard height similar to what is found in most residential houses. I recommend the Dometic 320 Full-Timer RV Toilet, # DOM87FR because of its elongated design over the round bowl design of the 310 Part-Timer, # DOM57FR.

  • Measurement Required To Replace a Dometic 300 Toilet With a Dometic 310 Toilet
    You will need to measure the rough in dimensions on your current Dometic 300 Toilet # DOM64FR in your Keystone Springdale 260BH. Your 300 only requires a rough in of 8-1/2" while the Dometic 310 Toilet # DOM57FR needs a 10" rough in measurement. You will need to measure the distance from the wall behind your toilet to the center of the toilet flange.

  • Recommended Replacement For A Dometic 300 RV Toilet
    You can replace your current Dometic 300 with the Dometic Full-Timer RV Toilet # DOM27FR ( # DOM87FR for white) if you like the elongated bowl design or you can replace it with a Dometic Part-Timer RV Toilet # DOM57FR if you just want another standard bowl design. Both of these toilets do require an 11" mounting distance to have enough clearance from the rear of the toilet seat to the wall. It really just comes down to your own personal preference.
