Shower installation spans a huge price range -- from a $1,500 prefab unit swap to a $15,000 custom tile spa shower. Understanding the categories helps you set realistic expectations.
Prefab shower unit replacement
Replacing an existing shower stall with a new prefab fiberglass or acrylic unit: $800-$1,500 for the unit, $500-$1,000 for labor, $200-$500 for plumbing connections. Total: $1,500-$3,000. This is the most affordable option and can typically be completed in 1-2 days.
Tile shower installation
Custom tile shower with cement board waterproofing, tile surround, and new fixtures: $3,000-$8,000 for a standard 36x36 or 36x48 shower. The premium is for the tile work itself and the waterproofing membrane -- both require skilled labor. Large walk-in showers run $6,000-$15,000.
Plumbing and fixture costs
Basic shower valve: $150-$300. Thermostatic valve with separate volume control: $400-$1,200. Rainfall showerhead with body sprays: $400-$1,500 for fixtures. If moving drain location or adding a new shower where one didn't exist, rough-in plumbing adds $1,500-$3,500.
Converting a tub to a shower
Tub-to-shower conversions are popular in homes where a large soaking tub in the primary bath gets no use. Cost: $1,500-$5,000 depending on tile vs. prefab and whether the drain needs relocation. This often increases the home's appeal to buyers in the 35-65 demographic.
Bottom line
For a functional shower replacement, budget $1,500-$3,000 for prefab or $4,000-$8,000 for custom tile. The custom tile option delivers a significantly better result and higher resale value.
