Hey there, tiny house enthusiast! I’m so glad you’re here—I’ve been helping folks like you navigate the world of tiny living for years, and I love sharing what I’ve learned. One of the biggest questions I get is about tiny house toilets: what types are out there, and do these homes even have bathrooms?

Let’s explore everything you need to know about tiny house toilets, with a deep dive into tiny homes composting toilet options and why they’re often the best tiny house composting toilet choice. I’ll also cover why toilets matter and how common bathrooms are in tiny houses, so you can buy with confidence.

How Common Are Bathrooms in Tiny Houses?

I’ll start with a question I hear a lot: do tiny houses have bathrooms? From my experience, about 90% of tiny houses in the USA have a bathroom. I’ve toured so many—from 150-square-foot trailers to 500-square-foot backyard setups—and most include a space for a toilet, sink, and shower. Builders know it’s a must for most buyers.

I visited a tiny house community in Oregon once, and even the tiniest 120-square-foot home had a bathroom. “It’s non-negotiable,” one owner told me, and I totally get it.

Why You Need a Toilet in a Tiny House

A toilet isn’t just a luxury in a tiny house—it’s what makes it a home. I’ve seen how a good bathroom setup, especially with reliable tiny house toilets, changes everything. It gives you privacy and comfort, so you’re not trekking to a shared facility or outhouse.

I helped a couple in Florida design their 300-square-foot tiny house, and they said, “A toilet makes this feel real—not like we’re camping.” It’s about creating a space where you can truly live, whether full-time or as a weekend retreat.

Different Types of Tiny House Toilets

Standard Flush Toilets

Let’s kick off with standard flush toilets—the kind you see in most homes. They use water to flush waste into a sewer or septic system. I’ve seen these in larger tiny houses on foundations, like a 400-square-foot home in Texas. They’re familiar and easy to use, but they need plumbing and a water supply, which can be tough for mobile tiny houses.

Composting Toilets: A Tiny House Favorite

Now, let’s talk about tiny homes composting toilet options, because they’re a top pick for tiny living. A tiny house composting toilet breaks down waste into compost naturally, without water. I’ve recommended these to so many off-grid buyers in places like Oregon and Colorado.

Models like the Nature’s Head and Sun-Mar Excel are some of the best tiny house composting toilet options out there. The Nature’s Head, around $1,000, is compact and easy to use. A client in Washington raved, “It’s so simple—no water bills!” The Sun-Mar Excel, about $1,800, has a fan to control odor, which I’ve seen work wonders in a 250-square-foot tiny house.

Why are tiny house composting toilets a good option? They don’t need plumbing, which cuts costs in a tiny house build. They’re eco-friendly, saving up to 8,000 gallons of water a year for a family of two.

I’ve seen them installed for as little as $800, compared to $2,000 for a plumbed system. Sure, you’ll empty the compost every few weeks, and odor can be an issue if you don’t maintain it—peat moss helps—but the benefits often outweigh the hassle.

Incinerating Toilets for Tiny Houses

Incinerating toilets are a high-tech choice—they burn waste into ash using electricity or gas. I’ve seen these in luxury tiny houses where owners want a waterless option. They’re compact and odor-free but cost $2,000 to $5,000. A client in California loved hers, saying, “It takes up so little space!”

Portable Camping Toilets

Portable camping toilets are the bucket-style ones you’d take on a trip. They use chemical bags to manage waste and are super small. I’ve seen them in 100-square-foot tiny houses on wheels, where space is tight. They’re cheap but not great for full-time use—emptying them gets old fast.

A tiny homes composting toilet is a better long-term choice, offering a more sustainable solution without the constant bag changes.

Macerating and Vacuum Toilets

Macerating toilets grind waste and pump it through small pipes to a tank or sewer. I’ve suggested these for tiny houses with tricky layouts, like a backyard ADU. Vacuum toilets, like on airplanes, use suction and minimal water. I’ve only seen them in custom builds—they’re efficient but pricey. Both need power, which can be a drawback.

Dry Flush and Chemical Toilets in Tiny Houses

Dry flush toilets seal waste in foil bags without water. I saw one in a 200-square-foot tiny house in Colorado, and the owner said, “It’s like magic—no mess!” Chemical toilets use chemicals to break down waste and control odor, often for short-term use during moves. Both are portable, but the cartridges or chemicals add up.

Bidet Toilets and Pit Latrines in Tiny Houses

Bidet toilets add a water spray for cleaning, which I’ve seen in modern tiny houses for a luxe feel. They need plumbing, though, which can be tricky. Pit latrines or outhouses are the old-school option—a hole in the ground with a seat. I’ve seen them near rural tiny houses in Florida, but they’re not ideal for daily use. For a more practical choice,

Tiny House Bathroom Ideas Featuring Toilets

I love sharing tiny house bathroom ideas to make your toilet setup shine. Pair a tiny house composting toilet with a corner sink and a wet bath—a shower space with a drain in the floor. I’ve seen this in a 200-square-foot tiny house in California, and it saved so much room. Add a small window for ventilation, because moisture builds up fast.

For a modern look, use white or gray tiles to make the space feel bigger, and add wooden accents for warmth. A sliding barn door can hide the toilet area, which I saw in a Florida tiny house—it looked sleek and saved space.

Practical Tips for Your Tiny House Toilet Setup

I’ve got a few tips to make your tiny house bathroom layout work. First, ventilate well—a fan or window keeps things fresh, especially with a tiny house composting toilet. I’ve seen mold issues without airflow, so don’t skip this. Use vertical space—shelves above the toilet can hold towels.

Lighting is key too—I love LED strips around a mirror for a bright touch. A buyer in Texas told me, “It makes my bathroom feel like a spa.” If you’re using a composting toilet, keep peat moss nearby for odor control—it’s a small step that makes a big difference.
