Most Gruber Shower Pan models uniquely include a popular aesthetic design feature referred to as a inside shower sidewall camber (or chamfer). The curved sidewall is found in the shower "bowl" - just below the drip edge of the shower pan.

The illustration below compares a shower pan with straight edges to a shower pan with a camberred (or chamferred) sidewall.

Gruber Shower Pans with this Camberred/Chamferred Sidewall include the 1054 Series, the 1052 Series, and the 1051 Series.
