HOROW T0338W Compact One Piece Toilet, ADA Chair Height 17.3", Elongated Bowl, Dual Flush 0.8/1.28 GPF, White, 12 Inch Rough-In
The HOROW T0338W Compact One Piece Toilet is designed to fit into smaller bathrooms without forcing you to give up on comfort. It measures 26.6 inches deep, 15 inches wide, and 26 inches high, so it tucks neatly into tight spaces. The one-piece build gives you a seamless look that is also easier to clean. There are no hard-to-reach crevices around the base, so you can just wipe it down quickly.
You get a 17.3 inch seat height, which meets ADA chair height standards.
This makes sitting down and standing up more comfortable for seniors, taller adults, or anyone who wants a easier time in the bathroom. The elongated bowl gives you extra room, and the seat is a soft-closing PP model that won’t slam shut. It is screw-fixed to the bowl too, so it stays firmly in place without shifting around.
The flushing system uses a siphon action and a fully-glazed 2 inch trapway. This helps move waste out with strong suction, so you don’t have to worry about clogs.
You have two flush options: 0.8 gallons for liquid waste and 1.28 gallons for solid waste. That is a water-saving design that still gets the job done on the first flush. It is a good balance between performance and conservation.
Installation is straitforward thanks to the large side access openings that make mounting the toilet to the floor easier. HOROW lets you pick between a 10-inch or 12-inch rough-in, so you can order the version that matches your existing plumbing layout.

Compact Toilet Buying Guide
Compact toilets save valuable bathroom space while providing reliable flushing performance and comfort. If you have a half-bath, a tiny ensuite, or just want more elbow room in your main bathroom, teh right model makes all the difference. But with so many options out there, how do you choose? We’ve tested and compared the best compact toilets to help you find one that fits—literally and figuratively.
Bowl Shape and Length
Your first big decision is round or elongated. Round bowls are shorter—usually about 16 to 17 inches from the tank to the rim—so thay fit tight spots like under a window or behind a door. But elongated bowls offer more seating area, which is nicer for adults. The trade-off? They need about 2 more inches of space. Measure your rough-in distance (the space from the wall to the toilet’s mounting bolts) before you buy. A standard 12-inch rough-in is common, but double-check.
Flush Power and Water Efficiency
Don’t let the small size fool you—a compact toilet should still flush strong. Look for models with a pressure-assisted or gravity-fed system that uses 1.28 gallons per flush (GPF) or less. That’s the WaterSense standard, and it saves water without clogging. We’ve seen some compact toilets struggle with solid waste, so read reviews about “real-world” flushing. A dual-flush option (0.8 GPF for liquid, 1.28 GPF for solid) is a smart choice for families.
Height and Comfort for All Users
Compact doesn’t mean uncomfortable. Standard toilet height is about 15 inches, but “comfort height” models at 17 to 19 inches are easier to sit down and stand up from. If you’re tall, have mobility issues, or share the bathroom with kids, choose a height that works. We found that a 17-inch compact toilet feels surprisingly roomy, even in a small space. Test the sitting height if you can—or check the spec sheet carefully.
Installation and Maintenance Ease
You’ll want a toilet that’s simple to install, especially if you’re a DIYer. Look for models with a pre-attached wax ring or a no-wax seal system—they save time and mess. Also, check how easy it is to replace parts like the flapper or fill valve. Some compact toilets have hidden trapways, which look clean but are harder to snake if they clog. Stick with a straightforward design if you want less headache down the road.
Frequently Asked Questions About Compact Toilet
What exactly is a compact toilet?
A compact toilet is a smaller version of a standard toilet. It’s designed for tight spaces. Think small bathrooms, powder rooms, or RVs. They usualy have a shorter depth or a smaller overall footprint. This makes them fit where a regular toilet wouldn’t.
How much space do I need for a compact toilet?
You need to measure your bathroom first. Most compact toilets need about 24 to 28 inches of depth. The width is often the same as a standard toilet, around 14 to 16 inches. Always check the product specs. Leave at least 15 inches of clearance from the center of the toilet to any side wall.
Do compact toilets flush well?
Yes, thay do. Many modern compact toilets have powerful flushing systems. They use less water than older models. Look for a toilet with a good flush rating. You want something that clears the bowl in one go. Don’t worry about performance just because it’s smaller.
Are they comfortable to sit on?
Comfort can vary. Compact toilets often have a lower seat height. This is around 15 to 16 inches from the floor. Standard toilets are usually 17 to 19 inches. Some people find this fine. For taller users, it might feel a bit low. Check the seat height before you buy. You can also get a comfort height compact model.
What’s the difference between round and elongated compact toilets?
Round bowls are more compact. They save about 2 to 3 inches in depth. Elongated bowls are a bit longer and oval-shaped. They offer a bit more room. For the tightest spaces, go with a round bowl. For a little more comfort, choose an elongated one if it fits.
Can I install a compact toilet myself?
Yes, you can. It’s a common DIY project. You need basic plumbing skills. The steps are similar to installing a standard toilet. Just make sure your rough-in distance matches the toilet. That’s the distance from the wall to the center of the floor flange. Most are 10 to 12 inches.
Are compact toilets more expensive?
Not usualy. Prices are similar to standard toilets. You can find budget-friendly options and higher-end models. The cost depends more on the brand and features. Things like dual flush or a soft-close seat can raise the price.
Last Thoughts Before You Buy
You’ve thought about your space limits, and now it’s time to decide. A small toilet can fit into tight corners or slim nooks where a standard one just won’t go. Look for models with a comfortable seat height and a good flush system—nobody wants weak flushing. Check the rough-in measurement to make sure it lines up with your plumbing. Also, think about ease of cleaning: a smooth surface and simple design help a lot. Pick one that matches your style, but don’t forget to read reviews from real users. They often point out details you might miss, like noise levels or installation quirks. Your small bathroom can still feel roomy and work well with the right choice.
When you narrow down your options, focus on what fits your daily needs best. A round bowl saves more space than an elongated one, but elongated can feel more comfortable for some people. You don’t have to give up features like a soft-close lid or water-saving options just because the room is small. Many modern designs offer both efficiency and comfort. So take your time, measure twice, and pick a compact toilet that makes your bathroom functional and easy to move around in. Your space will thank you for it.
