Bathroom Remodeling Cost Guide

Bathrooms seem like straightforward rooms to remodel. Then the tile comes off, the plumbing plan changes or a 1980s wall reveals work that needs correction before anything new can go in.

That is why bathroom remodeling costs in Des Moines can vary so widely. A simple refresh may involve paint, fixtures and a vanity. A full remodel may include design, planning, waterproofing, plumbing, electrical, tile, permits and careful coordination in one of the most heavily used rooms in the home.

In this guide, you’ll learn what a bathroom remodel actually costs in the Des Moines metro, budgeting by bathroom type, what costs are often overlooked in estimates and what bathroom remodeling ROI looks like.

How Much Does a Bathroom Remodel Cost in Des Moines?

A full bathroom remodel in the Des Moines metro typically starts around $35,000, with many hall baths and primary bathrooms landing between $50,000 and $100,000. Larger primary suite remodels with layout changes, custom tile, specialty fixtures and higher-end finishes can reach $150,000+.

Smaller powder room updates may cost less because they do not include a shower, tub, waterproofing system or extensive tile work. The $5,000-to-$15,000 ranges you’ll see online are surface-level updates: paint, a new vanity, maybe a toilet swap. They’re real options, but they’re not the same project as a comprehensive design-build remodel.

Bathroom Renovation Cost Per Square Foot

A full bathroom remodel in the Des Moines metro typically costs $700 to $1,500 per square foot, with primary suites toward the upper end because of the fixture density.

Remember, a 35 sq ft bathroom can include 80 sq ft of tile, two plumbing rough-ins, a fan, three light fixtures, a vanity, mirror, toilet, shower and shower glass. The work-per-square-foot density in a bathroom is the highest of any room in the house. Additionally, bathrooms are labor-intensive in ways kitchens aren’t, due to custom tile work, waterproofed substrate and tight plumbing.

Tile selection, shower system, existing conditions and many more factors explain why two bathrooms that are the same size can have very different remodeling costs.

What Drives Bathroom Remodeling Costs

Bathroom remodeling costs are comprised of the materials and labor that are easily identifiable, along with some important remodel costs that are less visible. Design and planning, permitting, waterproofing, and contingency all help protect the project before construction begins. Any budget that doesn’t account for these should be looked at skeptically.

Design & Planning

For many bathroom remodels, design and planning can represent 5% to 10% of the construction cost, depending on the complexity of the project.

At Red House Remodeling, this work is done in collaboration with our clients with one of our experienced, Certified Kitchen & Bath Designers. That means homeowners are not left trying to piece together layout, tile, fixtures, lighting and construction details on their own.

Vanity, Cabinetry and Countertops

For many bathrooms, this includes a double vanity, quartz counters, premium semi-custom cabinetry, mirrors, storage features and hardware.

Shower, Tub, Tile and Waterproofing

This includes the walk-in shower, glass enclosure, tile floor, shower walls, niches or accent tile, waterproofing and sometimes, a freestanding tub.

A properly installed waterproofing system for a shower may add $2,000 to $4,000 to the project, depending on the size and complexity of the shower. The reason it matters is simple: water damage behind tile can be far more expensive than doing the waterproofing correctly the first time. A shower that looks beautiful on the surface still needs the right prep, materials and installation behind the walls.

Plumbing, Electrical, Lighting and Ventilation

This covers plumbing fixtures, toilets, rough-in work, lighting updates, outlets, heated floors, bath fans and other behind-the-wall improvements.

Permits and Approvals

Permit costs often fall between $150 and $500, depending on the city and scope of work.

Cosmetic updates, such as paint, hardware or a simple fixture swap may not need permits. Once a bathroom remodel involves moving plumbing, updating electrical, changing ventilation or altering the space more substantially, permitting becomes part of the project.

Contingency

For most bathroom remodels, homeowners should plan for a 10% to 15% contingency. Older homes, especially those with past remodeling work or unknown conditions behind the walls, should lean closer to 15%.

A contingency is not a sign that the project is poorly planned. It is part of responsible remodeling. It gives the homeowner and remodeler flexibility if hidden plumbing issues, framing concerns, subfloor damage, or selection upgrades come up during the process.

Red House Remodeling helps homeowners think through design, scope, permitting, waterproofing, and construction details before work begins with our design-build process. That front-end planning makes it easier to understand the real investment, compare options clearly, and move into construction with fewer surprises.

ROI: What a Bathroom Remodel Returns at Resale

Bathroom remodels in the Des Moines metro typically return 30 to 40 percent of their cost at resale, with mid-range projects recouping the highest percentage and luxury primary suites recouping the lowest.

The current Cost vs. Value Report consistently shows:

• Mid-range bathroom remodels recouping 58 percent
• Universal design remodels (curbless showers, grab bar blocking, wider doors) recouping 42 percent and trending up
• Upscale primary suites recouping 34 percent

For homeowners who plan to stay in their home, ROI should not be measured only at the closing table. The bathroom you use every morning affects your routine, comfort, privacy, storage, accessibility and overall enjoyment of your home. A better layout, a safer shower, warmer floors, improved lighting and more functional storage can make everyday life easier for years.

That quality-of-life return is often the reason homeowners choose to remodel in the first place. Resale value matters, but so does creating a bathroom that works better for the way you live now.

Final Bathroom Budget Takeaways

A realistic bathroom remodel budget should include more than the products you can see in the finished space.

Vanities, tile, plumbing fixtures, lighting, shower glass and heated floors all shape the final investment. But so do the less visible parts of the project: waterproofing, plumbing and electrical updates, permits, design, project planning and contingency.

Before comparing estimates, make sure the budget accounts for:

• Finish selections, including cabinetry, countertops, tile, fixtures, glass and flooring
• Technical work, including plumbing, electrical, ventilation, waterproofing and any fixture relocation
• Planning costs, including design, permits, project management and a 10% to 15% contingency

If each of those categories has a real number behind it, you have a more complete picture of your investment in your home. If categories are missing, the estimate can still be a starting point.

Providing an Honest Bathroom Budget

Bathrooms (and especially primary suites) are some of the most rewarding rooms we design and build throughout the Des Moines metro.

Two things shape the way we price a bathroom. First, we focus on up-front planning. Things like tile layout, lighting plan, plumbing layout, and glass details are all finalized in design (not on the jobsite). That keeps the budget accurate and the timeline predictable. Second, we’re a small, experienced owner-led team where trades sequence cleanly through the project and corners are never cut.

We’d rather give you the real number on day one and beat it than win the project with a number nobody could actually deliver.
