Dry Walls, Better Layouts, and a Bathroom That Works Every Morning
Residential code calls for a bathroom exhaust fan rated at 50 cubic feet per minute or more, and an undersized or missing fan is the reason so many older bathrooms around Dane County show peeling paint, soft drywall, and mildew in the corners. Greenline Construction, Inc.
provides bathroom remodeling in Marshall, WI
and across Sun Prairie, Columbus, Watertown, Lake Mills, and Deerfield, replacing showers, tubs, vanities, tile, and ventilation and reworking layouts in small and mid-size bathrooms.
We begin every remodel by evaluating the walls, subfloor, and plumbing behind the existing finishes, then install waterproofing membranes before a single tile is set. Accessibility features such as curbless showers, grab bars, comfort-height toilets, and wider doorways can be built in from the start. With 30+ years of remodeling Wisconsin homes and a 1-year labor warranty behind the work, we keep small bathrooms moving quickly. Request a consultation through our contact page to begin.
Bathrooms We Remodel and Upgrade
Shower and Tub Replacement
Worn tubs and leaking shower surrounds are removed down to the framing, and new units or tiled enclosures are installed over properly sloped, waterproofed substrates. Tub-to-shower conversions are a common request for households that rarely take baths anymore.
Tile Floors and Walls
Porcelain and ceramic tile are set over waterproofing membranes with movement joints and consistent grout lines, then sealed. Heated floor mats can be added beneath the tile so the bathroom stays comfortable on January mornings without running a space heater.
Vanity and Countertop Installation
New vanities are sized to the room and to the people who share it, with drawers and storage placed where toiletries actually live. Countertops, sinks, and faucets are installed and connected once tile and paint are finished around them.
Ventilation Upgrades
Exhaust fans are sized to the room, vented outdoors rather than into the attic, and wired to switches or humidity sensors that run long enough to clear steam. This single upgrade prevents most of the moisture problems that ruin bathroom finishes.
Layout Improvements for Small Bathrooms
Relocating a toilet, narrowing a vanity, or replacing a swing door with a pocket door can open a cramped bathroom without adding square footage. Larger mirrors, brighter lighting, and lighter tile finish the job of making it feel spacious.
Accessibility Features
Curbless showers, fold-down seats, grab bars anchored into blocking, comfort-height toilets, and wider doorways are integrated into the design rather than added as afterthoughts. The result is a bathroom that serves every age and ability without looking clinical.

FAQ's
What causes moisture damage in older bathrooms?
Inadequate ventilation, failed caulking around tubs and showers, and cracked grout that lets water reach the wall cavity are the usual causes. Once moisture gets behind the tile, drywall softens and framing begins to rot long before any stain shows on the surface.
How long does a bathroom remodel take?
Small bathrooms can often be completed in 1 to 2 weeks once demolition begins, while larger primary baths with custom tile and layout changes take longer. Having every fixture, tile, and vanity on site before the first day keeps that timeline honest.
Should I replace the subfloor when remodeling a bathroom?
Yes, if demolition reveals soft spots, staining, or delaminated plywood around the toilet, tub, or shower. Greenline Construction Inc. inspects the subfloor on every bathroom remodel in Marshall, WI and replaces damaged sections before waterproofing and tile go down.
Do I need waterproofing behind tile in a shower?
Absolutely. Tile and grout are not waterproof on their own, so a membrane or waterproof board must protect the framing behind shower walls and under the floor. Skipping this step is the most common reason remodeled showers fail within a few years.
How do I choose between a tub and a walk-in shower?
Consider how your household bathes today, whether children or future buyers will want a tub, and how much floor space you have. Many homes keep one tub elsewhere and convert the primary bathroom to a larger walk-in shower with a bench.
What ventilation is required in a remodeled bathroom?
Code requires an exhaust fan vented to the outdoors, typically rated at 50 CFM or more for a standard bathroom, unless an operable window meets the requirement. A humidity-sensing switch that keeps the fan running after showers is a worthwhile upgrade.
What accessibility features can be added during a remodel?
Comfort-height toilets, grab bars, curbless showers, handheld shower heads, lever handles, and wider doorways can all be built in without making the room look institutional. Greenline Construction Inc. plans blocking and clearances for these features during layout on Marshall, WI bathrooms.
What is involved in relocating a toilet or sink?
Moving either fixture means rerouting drain, vent, and supply lines beneath the floor or inside the walls, which sometimes requires opening a ceiling below. It is very doable during a complete remodel, and the layout gains often justify the extra plumbing.
Why Choose Us for Bathroom Remodeling
Waterproofing You Never Have to Think About
Membranes behind the tile, properly sloped shower pans, and sealed penetrations are installed before finishes cover them. That invisible layer is what keeps water out of your framing through decades of daily showers, steamy winters, and humid Wisconsin summers.
Damage Found and Fixed Before It Spreads
Soft subfloors, rotted framing, and failed caulking are exposed during demolition and repaired thoroughly rather than tiled over. You end up with a bathroom that is sound from the studs out, not just pretty on the surface for a season.
Small Bathrooms Back in Service Fast
Selections are finalized and materials are on hand before demolition, so most small bathrooms are out of commission for a short, predictable stretch. Larger primary bathrooms take longer, but you will know the whole schedule before work starts.
Layouts That Make Small Rooms Feel Bigger
Rather than defaulting to the existing footprint, we look at how a shifted vanity, a pocket door, or a reoriented shower would change the room. Often the most noticeable improvement costs less than a premium tile upgrade would.
Aging-in-Place Options Built In
Grab bar blocking, curbless entries, and wider clearances are easy to include during a remodel and expensive to retrofit later. We raise these options early in planning so your bathroom stays usable as your household's needs change over time.
Inspections and Warranty Handled
Plumbing and electrical changes are inspected as required, and the completed bathroom is covered by our 1-year labor warranty. If a fixture loosens or grout needs attention in the months afterward, one message brings us back to fix it.
A Bathroom That Stays Beautiful Behind the Tile
Most bathroom remodels are judged by what you can see, but the ones that last are decided by what you cannot: the membrane behind the wall, the slope of the pan, and the fan pulling steam outside. Greenline Construction, Inc. brings that standard to every bathroom around Marshall, WI, whether it is a compact hall bath or a full primary suite, and finishes it with fixtures and tile chosen for the way your family uses the room. If your bathroom is showing its age or simply never worked well, we would be glad to take a look. Reach out through our contact page to request a consultation.
