Bathroom Remodeling in Minnesota

In Minnesota, we plan bathroom remodeling projects in Minneapolis and Saint Paul. A bathroom remodel replaces fixtures and finishes and fixes what sits behind them: plumbing, waterproofing, subfloor and ventilation. It can be an update in the same footprint, a tub-to-shower conversion, or a full gut with a new layout. Because a bathroom handles water every day, the work you cannot see matters as much as the tile. It is worth doing when fixtures leak or fail, grout and caulk keep breaking down, the room is hard to use, or someone in the home needs safer access.

Minnesota context

Planning bathroom remodeling in Minnesota

  1. One statewide building code

    The Minnesota State Building Code is the minimum construction standard in every city, township and county, and it supersedes local building codes. Cities cannot require different building provisions, but a local government enforces the code only after adopting it by ordinance. The residential chapter adopts the 2018 International Residential Code with Minnesota amendments, published in 2020.

  2. Energy codes and climate zones

    Minnesota's residential energy code is based on the 2012 IECC with state amendments, in effect since February 2015. The commercial energy code follows ASHRAE 90.1-2019 and took effect in January 2024. It places 23 northern counties, including St. Louis County, in climate zone 7 and the rest of the state in zone 6A. The state adopts new energy codes every three years, so the edition in force is confirmed at permit time.

  3. Deep frost, heavy snow and ice dams

    State rules require footings at least 5 feet deep in northern counties and 3 1/2 feet deep in the rest of the state. Design ground snow loads are 60 pounds per square foot in northern counties and 50 elsewhere. Re-roofs need an ice barrier that reaches at least 24 inches inside the exterior wall. UMN Extension ties ice dams to heat loss, so attic air sealing and insulation are planned with roof work.

Permits

Bathroom work that moves or adds plumbing, adds electrical circuits or fixtures, changes ventilation or alters walls commonly needs a permit and inspections. Replacing a vanity or toilet in the same location may not. Rules differ by jurisdiction, so the local building department confirms what is required for your project.

Contractor licensing

Minnesota Department of Labor and Industry (DLI)

DLI licenses residential building contractors, residential remodelers and residential roofers. A license is needed to contract directly with the owner of a one- to four-unit residential property for work in more than one special skill, and roofing-only work needs a roofer, remodeler or contractor license. Remodelers may work only on existing structures, so building a new home or detached garage takes a residential building contractor license. Contractors with less than $15,000 in gross annual residential receipts may instead hold a certificate of exemption. Anyone contracting for electrical work needs a state electrical contractor license. Plumbing contractors need a state plumbing contractor or restricted plumbing contractor license, and only a full plumbing contractor license covers communities over 5,000 people. Saint Paul accepts the state residential contractor license but requires a city contractor license from contractors who hold only a state exemption or do one special skill. Before hiring anyone, look them up in DLI's iMS license search, where an active license shows a status of Issued.

Building permits

Permits in Minnesota

Building permits are issued by the city, township or county that has adopted the State Building Code by ordinance. The state code sets the construction rules everywhere, but each building department sets its own permit lists and process. Minneapolis requires a permit for almost all re-roofing, Rochester requires permits for re-roofing, re-siding and window replacement, and Saint Paul requires a permit for any exterior work in its Heritage Preservation areas. Electrical, plumbing and mechanical work usually needs separate permits. Minnesota Construction Pros confirms the permits for each address during planning, before work is scheduled.

What’s included

Bathroom Remodeling in Minnesota: scope and options

  • Demolition down to studs and subfloor where the condition calls for it
  • Shower and tub installation, including tub-to-shower conversions
  • Waterproofing behind tile in showers and other wet areas
  • Floor, wall and shower tile installation
  • Vanity, sink, toilet and faucet installation
  • Exhaust fan installation or replacement, vented to the outdoors
  • Plumbing and electrical updates coordinated with licensed trades where required
  • Wall blocking for grab bars, plus lighting, mirrors and accessories

Common options

Tub, shower or both
Keep a tub for bathing, convert to a walk-in shower for easier access, or install a tub and shower combination.
Shower base
A prefabricated pan installs quickly and simply. A tiled base allows custom sizes and low or curbless entries but involves more steps.
Wall surfaces
Tile, solid-surface panels or acrylic surrounds. Panels have few grout lines to clean, while tile offers more design choice.
Vanity style
Freestanding, wall-hung or built-in, with one or two sinks, sized to the storage you need and the space around it.
Accessibility features
Grab bars, a handheld shower, a bench, lever handles and a comfort-height toilet can be installed now or planned with wall blocking for later.

What this service does not cover

  • Remediation of widespread mold, which is handled by remediation specialists
  • Asbestos or lead-based paint abatement, which is handled by certified specialists
  • Replacing main water or sewer lines outside the bathroom
  • Repairs to water damage in rooms below the bathroom, unless added to the scope in writing

Budget planning

What affects cost

  • Layout changes

    Moving the toilet, shower or drains means more plumbing and floor work than keeping fixtures in place.

  • Shower type

    Custom tiled showers with niches, benches or curbless entries take more labor than prefabricated units.

  • Tile selection

    Tile size, material, pattern and how much of the walls are covered all affect labor and materials.

  • Subfloor and framing condition

    Water-damaged subfloor or framing has to be repaired before new finishes can go in.

  • Ventilation

    Adding or rerouting an exhaust fan so it vents outdoors can require work through walls, ceilings or the attic.

  • Fixtures and glass

    Shower valve types, specialty fixtures and custom glass doors vary widely.

  • Access and staging

    Tight rooms, upper floors and homes with only one bathroom affect how the work is sequenced.

Scheduling

What affects the schedule

  • Whether this is the only bathroom in the home
  • Custom shower glass, which is measured after tile is complete
  • Special-order vanities, tile and fixtures
  • Inspection timing for plumbing and electrical rough-in
  • Drying and curing time for waterproofing, mortar and grout
  • Water damage found after demolition

How to prepare

  • If this is your only bathroom, arrange another place to shower during the key stages
  • Remove toiletries, towels, rugs and anything stored in the vanity
  • Choose tile, vanity and fixtures early so they arrive before demolition
  • Note any current leaks, ceiling stains in the room below, or soft spots in the floor
  • Think about future needs, such as grab bars or a step-free shower

Process

How Bathroom Remodeling Projects Work

  1. 1

    Consult

    We look at the room, check for signs of leaks and soft spots in the floor, and talk through who uses the bathroom and how. Storage and accessibility needs come up here.

  2. 2

    Plan

    We settle the layout, tub or shower, tile, fixtures and ventilation, and write down the scope. Fixtures and tile are selected and ordered before demolition so the room is not left open waiting on materials.

  3. 3

    Build

    Demolition, plumbing and electrical rough-in, and inspections come first. Waterproofing is installed and checked before tile covers it, followed by fixtures, glass and trim.

  4. 4

    Enjoy

    A final walkthrough covers how fixtures and the fan work and how to care for grout, stone and glass. Punch-list items are completed before closeout.

Questions

Bathroom Remodeling FAQs

Can I convert my tub to a walk-in shower?

In most bathrooms, yes. The drain location, floor framing and wall conditions decide how simple it is. A low or curbless entry takes more floor work than a shower with a standard curb.

Why does waterproofing matter if tile resists water?

Grout and many tile materials let some water pass through over time. A waterproofing layer behind the tile keeps that water out of the walls and subfloor, where it would otherwise cause rot and mold.

Do I need a bathroom exhaust fan?

A fan that vents outdoors removes moisture that would otherwise collect on walls, ceilings and inside cabinets, leading to peeling paint and mold. Whether a fan is required depends on local code and whether the room has a window that opens.

What if this is my only bathroom?

The work can be sequenced to limit how long the toilet and sink are out of service, but there will be stretches without a working shower. Decide where you will shower during those stages before work starts.

Should I choose a prefabricated shower or tile?

Prefabricated units install faster and have few seams to clean. Tile gives more size, shape and design choices and allows niches and benches. Both perform well when installed correctly.

Can grab bars be added later?

Yes, if solid blocking is installed inside the walls during the remodel. Adding blocking while walls are open is simple compared with cutting into finished tile later.
