Remodeling a bathroom in Sioux Falls

A bathroom remodel in Sioux Falls has to deal with some of the hardest water in the region, very cold winters and city licensing rules that are different from many places.

The city's contractor license

The City of Sioux Falls requires a Residential Building Contractor license of anyone doing work on one- and two-family homes and townhomes in the city that needs a building permit. The license takes a passing score on an open-book code exam, a $20,000 compliance bond and at least $300,000 of general liability insurance. The city also requires its own license for contractors doing plumbing, electrical or mechanical work. Ask the contractor which licenses they and their subcontractors hold, and who pulls each permit.

Doing your own plumbing

Under South Dakota law, a homeowner may install plumbing in the single-family house where they live, and the homeowner permit covers the house only. If you plan to do some of the work yourself, ask the city about permits and inspections before you start, and make sure your contractor's scope and yours don't overlap.

Hard water

The City of Sioux Falls' annual water report lists average total hardness of 250 ppm for city water, with a suggested softener setting of 15 grains per gallon. Untreated, that water spots glass shower doors, clogs showerheads and leaves scale on tile and grout. A working water softener helps more than any finish. When choosing fixtures, ask about finishes that hide spots, glass coatings, and showerheads with flexible nozzles that are easy to descale.

Winter ventilation

NOAA's engineering weather data for Sioux Falls gives a 99% winter design temperature of −11°F. In deep cold, warm, moist bathroom air condenses on cold windows and exterior walls, and in attics if the fan is vented there. Ask for an exhaust fan sized for the room and ducted all the way outdoors, with an insulated duct through cold spaces so it doesn't drip back. Exterior walls with plumbing need insulation on the cold side of the pipes.

Waterproofing

The tile isn't the waterproofing; the membrane behind it is. Ask what system the contractor uses, whether they flood-test the shower pan, and how they'll handle the niche and bench.

Getting comparable bids

Ask every contractor for the same scope: demolition, plumbing changes, waterproofing, tile, fixtures, electrical, ventilation and trim. Ask how long the room will be unusable, what happens if they find water damage behind walls, and how payments are tied to finished stages.
