Mobile Home Toilet Parts and Replacements

Yes, in a few ways. Most mobile homes use the same 12-inch rough-in as a site-built house, but the toilet itself is often lower, with a smaller bowl. Older homes also came with bone china, which is hard to find in regular stores. We carry white and bone toilets, along with the seats, tanks and repair parts to match.

It depends on your space. Standard and mobile home toilets both use a 12-inch rough-in, so the drain lines up. In a tight mobile home bathroom, though, a standard toilet can hit the door or crowd the room. Our bowls are sized for mobile home bathrooms, so you get a comfortable fit.

Yes. Mobile home toilets connect to the same drain and septic systems as site-built homes. Standard toilet paper is fine. The only exception is if your home is on a holding tank or an older small-diameter drain line. In that case, single-ply or septic-safe paper puts less stress on the system. If you are unsure about your drain line size, call us before ordering.

Round bowls take up about 2 inches less space front to back than elongated bowls. In a small mobile home bathroom, that 2” difference can ensure the door opens properly and provide standing room. The ADA toilet on this page has an elongated bowl and a taller seat, which suits larger bathrooms or anyone who wants a comfort height toilet. Measure your floor space before you choose.

Most seniors (and taller adults) find comfort height significantly easier to sit down on and rise from. ADA-compliant comfort height toilets measure between 17 and 19 inches from floor to seat, compared to the standard 15 inches. The White ADA Compliant Toilet on this page meets that specification. For reference, a standard chair seat is about 17 inches. If the toilet is being replaced as an accessibility upgrade, confirm your floor clearance allows for the slightly larger footprint of a comfort height bowl.

Measure the opening at the bottom of your tank. Most older mobile home toilets use a standard 2-inch valve, and newer or high-efficiency tanks use a 3-inch valve. To check yours, drain the tank, lift the flapper and measure the opening. We stock both the standard 2-inch Flush Valve and the 3-inch Flush Valve. Not sure? Call 1-800-368-6208 with your tank model number and we will tell you the size.

Some plumbers turn down mobile home work because the plumbing is different from a site-built house. There is less room under the floor, the drains are set up differently, and the supply lines often need special fittings. We have worked with mobile home plumbing since 1994 and can confirm the right part before you order: 1-800-368-6208. Having the right part on hand also saves your plumber a second trip.

Yes, if the bowl is undamaged. The Tank and Lid Sets on this page are sold separately and fit standard mobile home toilet bowl connections. You will need to match the color (white or bone) and confirm the bolt pattern on your existing bowl before ordering. If the tank cracked but the bowl is sound, a tank swap is significantly cheaper than a full replacement. Call us with your existing bowl model if you are unsure which tank set fits: 1-800-368-6208.
