Cement board typically costs more than drywall to buy and install, especially when labor, fasteners, and waterproofing are included. For a standard interior wall, installed drywall often runs $1.50-$3.50 per square foot, compared with about $4-$10 for cement board before tile; room conditions, board thickness, and finish level affect both prices.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Drywall, installed | $1.50/sq ft | $2.50/sq ft | $3.50/sq ft | Standard 1/2-inch board, taped and finished |
| Cement board, installed | $4/sq ft | $6.50/sq ft | $10/sq ft | Board installation only; tile excluded |
| Drywall materials | $0.40/sq ft | $0.70/sq ft | $1.10/sq ft | Board, joint compound, and tape |
| Cement board materials | $0.80/sq ft | $1.30/sq ft | $2.25/sq ft | Board and compatible fasteners |
What cement board and drywall cost per square foot
For a 100-square-foot wall, drywall installation commonly totals $150-$350, while cement board installation runs roughly $400-$1,000. These estimates cover ordinary wall preparation and installation, not paint, tile, major framing repairs, or extensive waterproofing. Small jobs can cost more per square foot because contractors may charge a minimum service fee.
Drywall is generally the lower-cost choice for dry interior areas, while cement board is a more durable tile substrate. Rates assume a straightforward residential project with normal access and standard materials. Assumptions: U.S. midrange labor rates, wall framing in usable condition, and no tile installation.
How board, fasteners, and finishing shape each quote
Drywall is relatively quick to hang and finish. Cement board weighs more, takes specialized screws, and can require extra handling and cutting. Contractors may price it higher because installation is slower and the board’s seams need compatible mesh tape and mortar rather than standard drywall compound.
| Quote item | Drywall range | Cement board range | What changes the charge |
|---|---|---|---|
| Board and fasteners | $0.40-$1.10/sq ft | $0.80-$2.25/sq ft | Thickness, brand, and sheet size |
| Installation labor | $0.75-$1.75/sq ft | $2-$5/sq ft | Cutting, layout, and access |
| Seams and surface prep | $0.35-$0.90/sq ft | $0.50-$1.50/sq ft | Finish level or tile-ready prep |
| Waterproofing | $0-$0.50/sq ft | $0.75-$2.50/sq ft | Membrane type and wet-area coverage |
Ask whether the quote includes seam treatment and waterproofing, since those items can materially change the cement-board total.
Room moisture, board thickness, and wall size change prices
Drywall is suitable for most bedrooms, living rooms, and other dry spaces. Moisture-resistant drywall may be used in some damp areas, but it is not a substitute for an approved tile substrate or shower waterproofing system. Cement board is commonly used behind tile in showers and tub surrounds, where exposure demands a more moisture-tolerant backing material.
Thickness also matters: 1/4-inch cement board is commonly used over floors, while 1/2-inch board is typical for many walls. A 3-by-5-foot sheet covers 15 square feet, but small shower walls, niches, and plumbing cutouts increase waste and labor. Waterproofing is a separate system; cement board itself is not waterproof. A membrane or approved coating can add about $0.75-$2.50 per square foot.
Projects below 50 square feet may face minimum charges, while jobs over 300 square feet can benefit from better labor efficiency. Uneven framing, narrow access, demolition, or moving fixtures can push an estimate beyond typical ranges.
When drywall saves money and when cement board earns its cost
For painted walls outside wet zones, drywall usually offers the best value and is easier to repair. Cement board is typically unnecessary behind ordinary paint, and its weight and installation demands add expense without a practical benefit in a dry room. For tiled shower walls, using drywall to cut upfront cost can risk moisture damage if the assembly is not approved for that use.
Match the backing to the finish and exposure rather than choosing the cheapest sheet material. In a shower, compare complete assemblies, including board, waterproofing, and tile preparation; in a dry room, compare finished drywall quotes that include taping, sanding, and the specified finish level.
Three bathroom wall estimates show the cost difference
A 60-square-foot bedroom partition with standard drywall might cost $90-$210 installed, assuming no insulation or framing changes. At roughly $1.50-$3.50 per square foot, a basic finish is less expensive than a higher smooth-wall finish, which may require additional labor.
A 90-square-foot tub surround with cement board might total $360-$900 for board installation, plus approximately $68-$225 for waterproofing. Tile, grout, and tile-setting labor are additional. A 120-square-foot bathroom wall project combining 70 square feet of cement board and 50 square feet of drywall could run around $355-$875 before paint or tile, depending on local labor and finish requirements.
Separate substrate, waterproofing, and finish prices in each bid to compare equivalent scopes. These examples exclude demolition, disposal, plumbing changes, and sales tax.
How labor time and contractor rates affect installation
Drywall crews may hang and finish a straightforward 100-square-foot wall in roughly 6-10 labor hours, often spread across multiple visits for compound drying. Cement board installation for a similar area may take 8-14 labor hours, depending on cuts, framing, and waterproofing details. Local rates for drywall or tile-setting labor commonly fall around $50-$100 per hour.
Contractors may quote by square foot rather than hourly, and minimum charges of about $200-$500 are possible for a small repair or isolated wall. Confirm whether the estimate includes setup, cleanup, multiple finishing visits, and disposal. Labor estimate formula: labor hours multiplied by the contractor’s hourly rate.
Regional labor rates shift the installed board price
Material prices are relatively consistent nationally, but labor and overhead vary. Large coastal metros and high-cost cities may quote 15%-30% above national midrange prices. Smaller Midwestern or Southern markets may come in about 5%-15% below midrange, while remote locations can cost more if contractors travel or materials require special delivery.
For example, a cement-board job priced at $6.50 per square foot in a mid-cost market could reach approximately $7.50-$8.50 per square foot in a high-cost metro, before unusual prep. Use local quotes for budgeting, and compare the same square footage, board thickness, seam treatment, and waterproofing scope.
Lower the quote with accurate measurements and controlled scope
Measure each wall separately and subtract large openings only if the contractor uses net area pricing. Ask whether the estimate is based on wall area or sheet count, and have the contractor identify waste and minimum charges. Grouping several rooms into one visit can reduce mobilization costs when the work uses the same crew and materials.
Keep drywall in dry areas instead of extending cement board throughout the room, but do not remove required shower waterproofing to save money. Choose standard board dimensions and thickness where suitable, and avoid premium upgrades that are not required by the finish or local code. Two or three itemized bids can reveal whether the price difference comes from labor, waterproofing, or unnecessary scope.
