Romtec 1011 & 1011ES

DESCRIPTION: Meet the SST® Aspen Single. This versatile unit is Romtec’s fully customizable, single-user waterless restroom. CMU block and rebar construction makes the Aspen Single a structure that is built to last, and SST® ventilation ensures that odor will never harass an occupant. Our three price levels satisfy economic and budgetary concerns without sacrificing quality. You can choose our modern “shed” style design or opt for a more traditional roof extension. Every Aspen Single is ADA compliant. Our kit is easy to install and comes with step-by-step instructions and stamped and sealed plan sets, or Romtec can provide turnkey service.

STORM SHELTER UPGRADE: This restroom can be designed and engineered to meet storm shelter design standards rated for tornadoes and hurricanes, including the NSSA/ICC-500 and FEMA P-361 standards.
