Two 2.6-gallon tanks, a hand-operated bellows pump flush, and no plumbing or hookups required. Around 27 flushes per fill and a detachable waste tank you carry and empty by hand.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Thetford Porta Potti 135 is a self-contained portable toilet built for boats, campers, and anywhere a permanent head isn't in the cards. Two 2.6-gallon tanks, one for fresh flush water up top and one for waste down below, snap together into a single unit you can carry, use, and empty by hand. No plumbing. No hookups. No through-hull to cut. That's the whole appeal.\u003c\/p\u003e\n\u003cp\u003eThe flush is a bellows pump you work by hand. Push it a few times and clean water rinses the bowl. It's simple, and there's nothing electric to fail on you out there. You'll get around 27 flushes out of a full fresh tank before it's time to refill, which for most weekend crews is a couple of days of normal use. The waste tank holds the same 2.6 gallons. A couple aboard a 22-foot trailer-sailer can usually run three or four days before it needs emptying. Empty it more often than that if you can. A tank you dump daily smells a lot better than one you let sit.\u003c\/p\u003e\n\u003cp\u003eFootprint matters on a boat, and this one's compact. 15 inches long, 13.4 wide, and 12.2 tall. Before you buy, measure your space, especially the height. On a low-headroom cuddy cabin the 12.2-inch height can be the deciding factor, so check it first. It'll tuck into a V-berth on a 25-footer, but keep in mind a full unit is heavier and you'll want clear access to lift the waste tank out, so plan to empty it before it's brimming.\u003c\/p\u003e\n\u003cp\u003eOn the water, secure it. A portable toilet that slides around when the boat heels is no fun for anyone. A couple of straps or a simple mounting bracket keeps it put. The waste tank detaches from the base, so you carry just the bottom half to the pump-out or dump station and leave the seat and fresh tank aboard.\u003c\/p\u003e\n\u003cp\u003eKeep odors down with a few habits. Use RV or marine rapid-dissolve tissue, not thick household paper, because the bellows pump and the pour spout don't love anything that clumps. Add a holding-tank deodorant to the waste tank. Empty regularly. The seat gasket is the usual culprit if you start to notice a smell after a season or so, and it's a cheap seal to swap out once a year. In cold weather, a dab of lubricant on the waste valve keeps it from sticking.\u003c\/p\u003e\n\u003cp\u003eA few things this particular model leaves out. There's no water-saving hand sprayer and no tank level indicator. That keeps it simple and keeps the price down, and honestly, on a 2.6-gallon tank you get a feel for when it's full pretty quickly. If you want those extras, Thetford makes larger Porta Potti models that add them. For a compact, no-nonsense portable head on a small boat, an RV, a truck camper, or a hunting cabin, the 135 does exactly what it says.\u003c\/p\u003e\n\u003cp\u003eWho's it for? First-time boat owners who don't have a built-in head and don't want to commit to one. Trailer-sailers and small cruisers where every inch counts. Truck campers and pop-ups. Fishing cabins and job sites. Anybody who needs a real seat and a real flush without cutting into the hull for a full sanitation system. It's the kind of gear you buy once and forget about, then quietly appreciate every trip.\u003c\/p\u003e\n\u003cp\u003eCleaning is straightforward. Rinse the fresh tank now and then, flush a little clean water through the bowl, and give the waste tank a good rinse at the dump station. Between trips, store it empty and dry with the lid closed. Come spring, check that seat seal and the valve before the first outing and you're good to go.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e2.6-gallon fresh water tank paired with a 2.6-gallon waste holding tank, so you get real capacity in a portable package\u003c\/li\u003e\n  \u003cli\u003eHand-operated bellows pump flush rinses the bowl with clean water, nothing electric to fail\u003c\/li\u003e\n  \u003cli\u003eAround 27 flushes per full fresh tank, enough for a couple of days of weekend use\u003c\/li\u003e\n  \u003cli\u003eSquare front with a round seat for comfortable, familiar seating\u003c\/li\u003e\n  \u003cli\u003eCompact 15 in L x 13.4 in W x 12.2 in H footprint fits tight cuddy cabins and V-berths\u003c\/li\u003e\n  \u003cli\u003eWhite and medium gray finish that wipes clean and hides everyday wear\u003c\/li\u003e\n  \u003cli\u003eFully self-contained, no plumbing, no hookups, and no through-hull required\u003c\/li\u003e\n  \u003cli\u003eDetachable waste tank lifts off the base so you carry only the bottom half to the dump station\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Thetford Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eHow many flushes do I get per fill?\u003c\/summary\u003e\n    \u003cp\u003eAbout 27 flushes from a full 2.6-gallon fresh water tank.
