Fat Finger Construction builds bathroom additions in St. Petersburg, FL for homeowners who have simply outgrown the bathrooms they have. Many of the city's older houses, from the Historic Kenwood bungalows to the mid-century ranches off 34th St, were built with one bath, or one and a half, for the way people lived decades ago. Adding a full bath, a half bath or an en-suite for an existing bedroom is one of the most practical changes you can make to a home like that. It eases the morning rush, gives guests their own space, and makes the house work better for the long haul.
A bathroom addition in St. Petersburg has to hold up to Gulf Coast living. Heat and humidity are constant, summer afternoon storms bring heavy rain, and homes near Tampa Bay deal with salt air. That is why we pay close attention to ventilation, moisture-resistant materials, waterproofing behind the tile and a tight connection where the new space meets the old. Your new bath includes the framing, plumbing, electrical, fixtures, tile and trim, all planned as one job. If you live in Old Northeast, Crescent Lake, Snell Isle or anywhere along 4th Street N, call us for a free in-home estimate.
