The hillside streets of Bountiful, on the benches above Orchard Drive and climbing toward Bountiful Boulevard and the canyon road up to Mueller Park, are full of split-level and multi-level houses. Many of them have bathrooms on three different floor levels, and each half-story shift means the drain lines change direction inside the framing to get where they are going. Drain lines need consistent fall to work. When a floor sits only a few feet above the level below it, and part of that space is already taken by joists and ductwork, there is not much room left to gain the slope a relocated fixture would need.
In practical terms, that means the answer to "can we move the shower over there" depends entirely on what is under the floor. Shifting a shower drain two feet along an open joist bay may be simple. Shifting it across the joists, or to a spot where the line would have to cross a beam, may require furring down a ceiling in the room below or rethinking the layout. A contractor should trace the existing line and confirm the route before promising you a floor plan. Often a small adjustment to the design preserves the original drain run and saves both time and finished ceiling downstairs.
Two different kinds of venting matter in a bathroom, and both get complicated in multi-level homes. The exhaust fan needs a clear path to the outdoors, and in a split-level the roof above a given bathroom may be a long way off, or the nearest exterior wall may face the uphill side. What often gets installed instead is a long run of undersized flexible duct that sags, loses airflow, and sometimes just terminates in the attic. That moisture has to go somewhere, and in a cold attic it condenses, drips back, and eventually stains the ceiling below. Smooth-wall duct, kept short, sloped toward the exterior, and insulated where it crosses unconditioned space, solves it.
The plumbing vents are the other half. Every fixture needs one for the drains to flow properly and to keep trap seals intact, and on a hillside home the path from a lower-level bathroom up through the roof can be genuinely awkward. Depending on the layout, the options are tying into an existing stack, wet venting an adjacent fixture where local code allows it, or using an approved air admittance valve when a through-roof vent is not feasible. These are questions to settle during planning rather than mid-project, and permits generally apply once plumbing, electrical, or structure changes.
Remodeling an upper-floor bathroom means running a wet, dusty, noisy trade directly above rooms you use every day. Good crews plan for that. Floor protection along the entire path from the door to the stairs, a sealed dust barrier at the top of the stairs, covered furniture in the room below, and a written understanding of where debris exits the house. Expect some vibration and expect noise. Also expect that if drain or vent lines move, the ceiling below will need to be opened somewhere, and ask up front who is responsible for patching, texturing, and painting it when the bathroom is finished.
Waterproofing deserves extra attention on an upper floor, because the consequences of getting it wrong land in the room underneath. Failures behind tile rarely announce themselves. They show up years later as a soft spot in the floor or a stain spreading across the ceiling below, long after the crew is gone. Ask specifically about the membrane, how corners and the curb are handled, how penetrations are sealed, and whether the pan gets flood tested before tile is set. A contractor who answers those questions comfortably is telling you something useful. For referrals in Bountiful, call 801-644-9000.
A toilet drain is larger than a sink or shower drain and it has to maintain fall all the way to the stack. On an upper floor that pipe has to fit within the depth of the floor joists, and it cannot simply cut through them wherever convenient. Depending on joist direction and where the stack sits, relocating a toilet even a few feet can mean structural work or a furred-down ceiling in the room below.
If drain or vent lines move, usually yes, at least in sections. Access is often the only way to reroute a line correctly, and cutting a controlled opening is far better than working blind from above. Settle it before work starts: confirm in writing that patching, texture matching, and paint in the room below are part of the scope so it does not become an unwelcome conversation at the end.
Outdoors, always, through a roof cap or a wall cap with a functioning damper. Never into the attic, a soffit that draws air back in, or a crawlspace. On multi-level homes the shortest sensible route sometimes runs through a sidewall rather than the roof, which is fine. Use smooth-wall duct instead of long sagging flex, keep the run short, slope it toward the exterior, and insulate it through cold space.
