The all-new Aqua-Magic V is much more than a replacement for the Aqua-Magic IV. The new shape reflects a deeper bowl inside and a more home-like style for the RV bath. The Aqua-Magic V is more than 1-1/2" taller than Aqua-Magic IV and it's still lighter. The new larger single pedal is simpler and more comfortable to use. Halfway adds water; full activation flushes. Dimensions: 18.5"H x 15.1"W x 17.8"D. Lightweight and easy to install. White. Priced each
