How to choose the right one
-
Check rough-in size
Measure the distance from the wall to the toilet flange bolts. Most units require a 12-inch rough-in, but the DeerValley model fits a 10-inch rough-in. This difference matters for tight layouts. If your space is narrow, verify the exact measurement. A mismatch means the toilet will not fit. Always measure before purchasing. This spec determines if the unit fits your plumbing setup. Choose the rough-in that matches your existing hole.
-
Compare width and depth
Widths range from 13 to 16 inches. The HOROW HWMT-8733 is only 13.4 inches wide. The VANCOCO S1 is 16 inches wide. Depth varies from 23.5 to 28.8 inches. The CANEST model is 23.5 inches long. Narrower units save floor space. Longer units may not fit in small rooms. Check both width and length against your floor plan. Ensure there is clearance for the lid to open. Smaller dimensions allow for easier movement in tight bathrooms.
-
Select seat height
Standard height toilets sit around 27 to 28 inches tall. The HOROW HR-ST076W is 28 inches high. ADA height models are around 18 to 19 inches from the floor to the seat. The Vomlor model offers this accessible height. ADA height is easier for seniors or tall users. Standard height is typical for average adults. Choose based on user comfort and mobility needs. Check the seat height spec carefully. This affects ease of sitting and standing.
-
Choose flush type
Dual flush toilets offer two flush options. This saves water by using less for liquid waste. The DeerValley and HOROW HWMT-8733 both have dual flush. Single flush models, like the HOROW HR-ST076W, use one setting. Dual flush is more efficient. Single flush is simpler but uses more water. Decide based on your water conservation goals. Check the flush type in the specs. This feature impacts long-term water usage and environmental impact.
-
Decide on bowl shape
Round bowls are shorter than elongated ones. The BAYROLL and Casta Diva models have round bowls. They save space in the front. Elongated bowls offer more comfort but take more room. The HOROW HR-ST076W is not specified as round, so check its shape. Round bowls fit better in tight spaces. Consider user comfort versus space constraints. Choose round for maximum space savings. Choose elongated if space allows and comfort is priority.
