Replace, refinish, or convert
A structurally sound cast-iron tub in a Beaverdale, Sherman Hill, or Drake-area home can be refinished for a fraction of a replacement and hold 3–7 years. If the tub is cracked or the surround shows water damage, refinishing hides a bigger problem, Iowa's dramatic freeze-thaw cycles and summer humidity combined with attic-vented fans common in older intown stock accelerate slow leaks into subfloor rot.
In multi-bathroom Dallas and Polk county homes across West Des Moines, Ankeny, Waukee, Johnston, Urbandale, and Altoona, pricing a tub-to-shower conversion in parallel is worth it. Suburban DSM alcoves convert cleanly and the walk-in shower is usually the more-used fixture in a primary suite.
Tub types and installed cost in Greater Des Moines
Most DSM-area replacements are alcove tubs. Acrylic and fiberglass install fastest and dominate West Des Moines, Ankeny, Waukee, and Johnston subdivision stock. Cast-iron tubs are common in pre-1970 Beaverdale, Sherman Hill, Drake, Highland Park, and older East Des Moines stock.
- Acrylic alcove tub (most common): $1,900 – $4,400 installed
- Fiberglass alcove tub: $1,700 – $3,500 installed
- Steel enameled alcove tub: $2,300 – $4,700 installed
- Cast-iron alcove tub: $3,600 – $7,000 installed (weight + labor)
- Drop-in tub with new deck: $4,400 – $9,000 installed
- Freestanding soaking tub: $5,600 – $12,000+ installed (plumbing usually moves)
- Walk-in tub (accessibility): $8,200 – $15,800 installed

What a clean replacement scope includes
A like-for-like alcove swap in a DSM-area home should include tub removal and haul-away, valve and trim reuse or swap, new tub, new surround, plumbing reconnection, waterproofing, caulk and finish work, and disposal.
- Tub removal and haul-away (cast iron often cut in place in older intown stock)
- Valve and trim reuse or swap
- New tub set, leveled, and plumbed
- New three-wall surround (acrylic panels or tile)
- Waterproofing behind the surround
- New caulk seams and finish trim
- Optional: subfloor repair, drain relocation, vent-fan replacement
Des Moines-area cost drivers that push the range
The biggest swings across Greater Des Moines are subfloor condition, cast iron, and access. Pre-war Beaverdale, Sherman Hill, Drake, and Highland Park homes often have cast-iron drains, plaster walls, and prior moisture damage from decades of Iowa freeze-thaw cycles. Second-floor bathrooms above kitchens frequently need vent-fan rework at the same time.
Post-1990 West Des Moines, Ankeny, Waukee, Johnston, Urbandale, Altoona, and Clive subdivisions are cleaner, PVC drains, drywall, standard alcoves, and mostly full basements that make plumbing changes much easier than slab-only markets.
- Subfloor repair (common in pre-1960 intown stock): +$1,000 – $2,700
- Cast-iron drain replacement: +$700 – $2,000
- Drain relocation from below (basement access, standard in Central Iowa): +$800 – $2,000
- Cast-iron tub removal through narrow bungalow hallway (cut in place): +$400 – $900
- Tile surround instead of acrylic: +$2,300 – $5,300
- Vent-fan replacement (undersized/attic-vented common; critical for Iowa freeze-thaw + humidity): +$400 – $900
- Hard-water fixture upgrade (most Central Iowa water is hard): finish choice matters
- Des Moines / Polk / Dallas / Warren county permit + inspection: +$150 – $400

Timeline and disruption
A like-for-like acrylic alcove replacement is a 1–2 day project across Greater Des Moines. Cast-iron swaps or tile surrounds push to 3–5 days. Freestanding tubs with plumbing moves run 4–7 days, easier here than slab markets because virtually every DSM-area home has a full basement.
For single-bathroom DSM homes, most remodelers schedule replacements mid-week so the shower is back before the weekend. Confirm the day-by-day plan, dumpster placement, and permit timing before signing.

Frequently asked questions
Can I keep my existing surround and just replace the tub?+
Physically sometimes, practically almost never. Removing the tub breaks the waterproof seal at the surround base and the old surround rarely aligns with the new tub's flange. In older Beaverdale or Drake bathrooms the surround is usually as tired as the tub.
How long does bathtub replacement take in Greater Des Moines?+
1–2 days for a like-for-like acrylic swap. 3–5 days for cast iron or tile surround. 4–7 days when plumbing has to move.
Do I need a permit to replace a bathtub in Des Moines?+
Like-for-like swaps that don't move plumbing sometimes don't require a permit, but the City of Des Moines and Polk, Dallas, and Warren county jurisdictions want documentation once the valve or drain is touched. Iowa requires state-licensed plumbing contractors for plumbing changes. Ask the company to pull the permit and confirm the plumber's license.
Is a walk-in tub a good fit for aging-in-place in Des Moines?+
Sometimes. They keep bathing available but take 5–15 minutes to fill and drain while you sit inside. Most aging-in-place DSM-area homeowners prefer a low-threshold walk-in shower with a fold-down seat instead.
Will a new bathtub help or hurt resale in the DSM market?+
In multi-bathroom family-buyer segments (West Des Moines, Ankeny, Waukee, Johnston, Urbandale), a fresh tub is neutral to positive and buyers usually expect at least one. In East Village lofts and stay-put aging-in-place segments, walk-in showers typically add more value than a replacement tub.
