The HealthSmart Enhanced Comfort 5" Raised Toilet Seat Riser is meant for standard round toilet bowls and won’t fit elongated toilets. According to the manufacturer, it measures 15.7 inches long, 15.2 inches wide, and 6.1 inches high, with an opening size of 10.25 x 8 inches. They specifically say this riser isn't compatible with elongated toilets.

Our research supports this, noting that it fits snugly and securely on round toilets. For example, one person mentioned, "this fits securely and I feel safe when using it," while another pointed out it was the wrong shape for their elongated toilet, stressing the need to match the riser to a round bowl.

If you have an elongated toilet, look for a riser made for that shape. Always double-check the dimensions and compatibility info from the manufacturer to make sure it’ll work with your toilet.

It'll save you the hassle and ensure you get a good fit.
