Simple Project vs Renovators Supply: Toilets Compared

Two brands, one goal: a clean flush in a compact form

Simple Project and Renovators Supply are two toilet brands that often come up when shopping for a space-saving one-piece toilet. They share a similar formula: a one-piece ceramic body, a dual-flush siphon system, and dimensions that fit tighter bathrooms. But the details of the design, the flush performance, and the installation needs differ enough that a careful comparison is worth your time.

Both brands target the same kind of buyer: someone who wants a toilet that looks tidy, flushes efficiently, and does not eat up floor space. If that description fits you, this article walks through the key differences on one-piece construction, dual-flush operation, and compact sizing, then tells you which to pick based on your bathroom. For a broader overview, see our guide to compact one-piece toilets and guide to dual flush toilets.

One-piece design: why it matters

A one-piece toilet has a tank and bowl molded as a single unit, which removes the seam where a two-piece toilet can collect grime. That makes cleaning easier and gives the toilet a more streamlined silhouette. Simple Project and Renovators Supply both build their toilets this way, but the execution differs in how the tank meets the bowl and how the exterior surfaces are shaped.

Simple Project one-piece toilets usually have a smooth, skirted profile with no visible trapway. Renovators Supply also offers one-piece models, but some of their units keep a more traditional tank-to-bowl transition. The cleaning benefit of a one-piece toilet holds either way, but the skirted design is the easier one to wipe down.

Dual flush: two buttons, two water volumes

Both brands rely on dual-flush systems. A dual-flush toilet gives you a reduced flush for liquid waste and a full flush for solid waste. The reduced flush uses less water, which is the main reason these toilets help cut indoor water use. The EPA notes that toilets are the main source of water use in the home, accounting for nearly 30 percent of indoor consumption, and that replacing older models with efficient ones can reduce toilet water use by 20 to 60 percent.

On Simple Project toilets, the flush buttons sit on top of the tank and let you choose between the two volumes. Renovators Supply dual-flush models also use a two-button actuator. In both cases, the mechanism is a washdown or siphonic system depending on the model, so check the spec sheet for which flush type is listed. If you want to understand how the reduced flush and full flush work internally, read our guide on how dual flush toilets work.

The main practical difference between the two brands is not the dual-flush concept itself, but how the flush valve is tuned and how the bowl is shaped. A round bowl with a steep trapway tends to clear waste with less water, while an elongated bowl can improve comfort at the cost of a larger footprint. Keep that trade-off in mind when you compare models.

Compact dimensions: fitting a small bathroom

A compact toilet is usually defined by a shorter overall depth and a smaller footprint than a standard toilet. Both Simple Project and Renovators Supply make models that fit this description, but the exact dimensions vary by model. A common rule of thumb is to leave at least 15 inches from the centerline to any side obstruction, and you want enough clearance in front for comfortable use. The ADA standards set specific minimums for accessible facilities, which apply to commercial and public bathrooms, not private homes. See the sources for the official requirements.

Before you buy, measure your rough-in distance, which is the distance from the finished wall to the center of the floor flange. Most homes use a 12-inch rough-in, but 10-inch and 14-inch are also common. If your bathroom has a 10-inch rough-in, you need a toilet made for that distance. Read our article on toilet rough-in sizes to measure it correctly.

Installation and maintenance differences

One-piece toilets are heavier than two-piece models because the tank and bowl are cast as one unit. This makes installation a two-person job for most homeowners. Simple Project and Renovators Supply both fall into that category, so plan to have a helper on hand when you move the toilet into place.

A one-piece toilet also means fewer gasket surfaces. With a two-piece toilet, you have a tank-to-bowl gasket that can fail over time. With a one-piece, that joint does not exist, and the only seal you need to worry about is the wax ring at the floor flange. That simplifies future maintenance. If you are installing the toilet yourself, read our guide on how to install a toilet and the article on toilet flange basics to get the wax ring seated correctly.

Which brand should you pick?

If your bathroom is tight and you value a fully skirted look that is easy to wipe, a Simple Project compact one-piece model is a stronger candidate. These units tend to be shorter front to back, which matters in a powder room or a small bath where every inch counts.

If you prefer a more traditional one-piece profile and are willing to give up a little cleaning convenience for a more familiar look, a Renovators Supply toilet is worth a spot on your short list. Compare the exact bowl shape, rough-in, and flush volume on the models you are considering, and make sure the dimensions match your bathroom measurements.

Which brand is better for a small bathroom?

Simple Project tends to focus more on compact round-bowl models with a shorter overall length, which makes them a strong fit for tight spaces. Renovators Supply also makes compact models, so compare the exact dimensions on the units you are considering.

Do both brands have dual-flush toilets?

Yes. Both Simple Project and Renovators Supply offer dual-flush models with a reduced flush for liquid waste and a full flush for solid waste.

What rough-in sizes do these toilets support?

Most models from both brands support a 12-inch rough-in, and some support 10-inch. Check the spec sheet for the specific model to confirm the rough-in distance before buying.

Does a one-piece toilet flush as well as a two-piece?

A one-piece toilet can flush just as well as a two-piece when the trapway and flush valve are well designed. The flush performance depends on the bowl geometry and valve, not on whether the tank is separate.
