Options abound for both toilets and bidets. Available shapes include elongated, compact elongated, and round; different heights from standard (low) to ADA compliant to relaxed (chair height) are offered; and tankless, water-saving toilets are common in commercial venues. Upscale features include tornado flushing systems, integrated personal cleaning wands, ion-barrier surface treatment for bacterial control, and heated seats. Most toilets are made of porcelain but different materials are available. Both toilets and bidets may be specified in nearly any color.
