Plumbing the possibilities: Outdoor Kitchens, showers and baths

(BPT) – The trend toward outdoor living spaces that mimic the look, comfort, convenience and functionality of indoor spaces doesn’t have to stop at the backyard grilling station. A growing number of homeowners are exploring new additions to their outdoor spaces, including outdoor showers and powder rooms, and even garage entertaining areas anchored by sinks and wetbars!

While traditional plumbing techniques might once have limited just how homey you could make outdoor versions of kitchens and bathrooms, modern up-flush plumbing cost-effectively solves many problems. Above-floor macerating plumbing systems, like those from SFA Saniflo, U.S.A., allow the easy addition of a sink, shower or toilet outside, regardless of where plumbing lines are located inside. They also eliminate the need to cut through concrete if you’ll be placing your project inside a garage or on a concrete patio. Finally, the compact systems fit perfectly into smaller spaces, such as inside cabinets in an outdoor kitchen or in an outdoor powder room.

Here are four water- and drainage-dependent, outdoor living features that are more possible and popular than ever, thanks to up-flush plumbing.


Outdoor kitchens are in high demand, and have evolved to be true mirrors of their indoor counterparts. In addition to cooking facilities, such as a grill, cooktop, or pizza oven, today’s outdoor kitchen incorporates running water.

While a sink is an obvious necessity in outdoor kitchens, traditional plumbing can limit the location, configuration, size and capabilities of the space. Up-flush plumbing affords homeowners greater flexibility in designing an outdoor kitchen.

For example, using a Sanivite drain pump to remove wastewater more than 150 feet horizontally allows homeowners to install their outdoor kitchen where they desire, rather than having to rely on gravity and grading to move water. The pump is also capable of draining up to three separate fixtures, meaning you can have a sink and a dishwasher in your outdoor kitchen.


If you have a pool or are lucky enough to live near the beach, an outdoor shower can keep sand and other messes from getting tracked into the house. However, traditional plumbing practices can limit where you can locate your outdoor shower. Up-flush plumbing systems use pumps to move wastewater away from the drain, so you can locate an outdoor shower where it’s most convenient.

Products like the Sanishower fit into a small footprint and its low profile is easily concealed beneath the shower floor. Yet the system can handle drainage of up to 20 gallons per minute.


Whether you would like to add a wetbar to a patio or tucked into a corner of the garage, up-flush plumbing can make the process easy and cost-effective. Above-floor plumbing can handle wastewater removal in spots where no drain is present or possible. This means you can easily install a wetbar on a wooden deck, concrete patio or anywhere else where installing a traditional drain would be costly and inconvenient.

Powder rooms

When is an extra bathroom ever a bad idea? Imagine hosting a backyard barbecue or pool party without the need to make guests traipse through the house to reach the facilities, or wait in line inside the house while missing all the fun going on outdoors. Exterior bathrooms can solve those dilemmas, and up-flush plumbing can make it easy to add a toilet and sink outside the house.

While tying into existing traditional plumbing lines might require you to snuggle your outdoor powder room against the side of a house, above-floor plumbing allows you to position it virtually anywhere that’s convenient and appealing for your needs. The Sanicompact is a decorative one-piece system that combines a classic china toilet bowl with a built-in macerator/pump that can handle drainage from the toilet and a nearby sink.
