The best TOTO toilet for a small bathroom is the one that matches your existing rough-in and leaves enough front-to-back room—not simply the model marketed as compact. For a documented 10-inch rough-in, the TOTO Drake CST746CEMF(R)G.10 is a strong fit-oriented candidate: TOTO lists a 27 3/8-inch projection. Measure your bathroom and verify the exact SKU’s drawing before ordering.
How to choose the best TOTO toilets for small bathrooms
Start with two measurements that can rule out a toilet before you compare comfort or flush features:
- Rough-in: Measure from the finished wall behind the toilet to the center of the floor waste flange. Do not measure from the baseboard or unfinished framing.
- Available projection: Measure from that wall to the nearest limiting point in front of the toilet, such as a facing wall, vanity, or door path. Compare this with the model’s overall projection in its dimension drawing.
A toilet’s projection is only one part of the fit. Check the full drawing for bowl width and height, supply-line location, seat clearance, and room for the door to swing. Product specifications cannot establish whether the whole bathroom layout will work.
Which TOTO toilet fits a small bathroom?
For a measured 10-inch rough-in, the Drake CST746CEMF(R)G.10 is the clearest fit-oriented candidate in the cited TOTO specifications. TOTO lists a 10-inch rough-in and a 27 3/8-inch overall projection for that SKU. Its sheet also lists 1.28 and 0.8 gallons per flush (GPF). These are manufacturer specifications, not results from a comparative home test. TOTO Drake specification sheet, SS-01549 v.03

When a 10-inch rough-in TOTO toilet is the right choice
A 10-inch model is appropriate when the existing rough-in measures 10 inches and the selected model’s installation requirements match the bathroom. It is not a universal substitute for a 12-inch toilet: rough-in is determined by the waste-flange location, not by how close a toilet appears to the wall. If you are changing rough-in dimensions, ask a qualified plumber to assess the installation rather than assuming the toilet will fit.

Check fit before you order
- Measure the rough-in from the finished wall to the center of the floor flange. Match that measurement to the exact toilet SKU.
- Measure the current toilet’s projection and the available distance to the facing wall, vanity, and door path.
- Use the full dimension drawing to check overall width and height, supply-line clearance, seat space, and door swing.
- Confirm the exact model number and included bowl, tank, seat, and flush configuration. Do not rely on a family name alone.
- For a Drake 1G ultra-low high-efficiency configuration, ask a qualified installer to assess TOTO’s drainage conditions. TOTO’s cited sheet specifies adequate supplemental flows from other fixtures and a 4-inch inside-diameter drainline with a minimum 2% slope. TOTO Drake 1G specification sheet, SS-01516 v.03
