Who Buys Materials for a Remodel? Finishes and Allowances

How much of a kitchen or bath budget is finishes?

Enough that identical scopes price twice over. The useful figure is a spread, not an average: within one category, retail prices routinely run ten to one. Ceramic tile ranges from about a dollar per square foot to well over ten, and carpet from under ten dollars a yard to over forty.^[2]

Structural and mechanical work has far less room to move; code and the existing walls define it. Selections have no ceiling. That is why two proposals for the same kitchen differ more on their allowance pages than their scope pages, and why comparing bottom-line numbers without comparing selection levels tells you nothing. The companion guide on when an upgrade is worth it works the same trade-off in resale terms.

As of 2026 the NKBA puts the kitchen and bath industry near $228 billion, with professionally led remodeling spend forecast up 4.4 percent and elevated material costs named among the constraints on growth.^[3]

Who buys the materials for a remodel — the contractor or the homeowner?

Both, and the dividing line belongs in the contract. Typically the homeowner selects and often purchases the variable-priced visible finishes — cabinets, countertops, tile, plumbing fixtures, lighting, hardware — while the contractor supplies everything buried in the assembly.

The materials nobody sees

Behind a finished bathroom wall sit tile backer board, a bonded waterproof membrane, underlayment, blocking, fasteners, thinset mortar, grout, sealant and shims. These are specified against standards, not taste: bonded waterproof membranes are governed by ANSI A118.10, crack isolation membranes by A118.12.^[4] The Residential Code of Ohio separately requires tub and shower walls to be nonabsorbent to at least six feet above the floor.^[5] None of it appears in a finished photo, and all of it is the contractor’s to buy, because the contractor warrants the assembly.

What changes when you buy it yourself

Two things. Warranty: buy the product directly and the contractor may decline responsibility for problems with it.^[2] Lead time: whoever orders owns the delivery date and the damaged-in-transit replacement. Owner-supplied is reasonable — no markup, direct control — when selections are early and dates are shared with the crew. Otherwise an allowance inside a contractor-supplied scope is calmer. What sits behind older walls is covered in what older Columbus homes hide.

What is an allowance, and how do you know it is too low?

An allowance is a placeholder cost written into a fixed-price bid for an item not yet chosen — typically cabinets, countertops, tile, lighting, plumbing fixtures and flooring.^[2] It is the easiest place in a proposal to make a number look good, and low-balling allowances is an old trick to make a bid look attractive.^[2]

Read what the allowance covers

The cleaner structure is materials-only: the allowance buys the product, and installation labor sits inside the fixed price. Rolling labor in adds uncertainty and turns that portion into cost-plus.^[2] Ask which you have, in writing, and whether the figure is delivered cost including countertop fabrication, edge profiles, cut-outs and freight.

Verify it the only way that works

Price the actual product, at your quantity, at a real supplier, before signing.^[2] An allowance you have checked is a budget. One you accepted is a guess.

What Ohio law adds

For home construction services costing $25,000 or more, Ohio requires a written contract describing the goods and services, the anticipated dates and the total estimated cost.^[6] Where unforeseen but necessary excess costs exceed $5,000, the owner is entitled to notice and an estimate before that work is performed.^[6] The Ohio Attorney General advises that every contract require written approval for any change.^[7] An allowance overage is a change order.

Cabinets: stock, semi-custom or custom?

The tier names describe how the boxes are produced, not how well they are built. A well-made stock cabinet outlasts a badly made custom one.

Check certification rather than adjectives. Cabinets carrying the ANSI/KCMA A161.1 mark have passed a defined battery: shelves loaded to 15 pounds per square foot for seven days, wall cabinets to 600 pounds, doors cycled through a full 90-degree swing 25,000 times, drawers cycled 25,000 times under load, plus heat, cold, spill and stain tests.^[8]

Painted or stained

On a painted five-piece door the rail-to-stile joint will eventually show a hairline witness line, because the wood moves seasonally and the paint film does not. Manufacturers treat these as wood movement rather than a warrantable defect; the same movement occurs on stained doors but grain camouflages it.^[9] If that will bother you, specify MDF or veneered paint-grade doors.

Price pressure as of 2026

Imported kitchen cabinets and bathroom vanities have carried a 25 percent Section 232 duty since 14 October 2025.^[10] A scheduled increase to 50 percent was deferred to 1 January 2027, so the rate holds through 2026.^[11] Worth knowing before assuming an imported line is the value choice. See kitchen remodeling for the wider sequence.

Which countertop survives the way you actually cook?

Countertops are where the honest conversation has to happen: the most photographed material is the least forgiving.

Sealing marble does not stop etching

Marble, limestone, travertine and onyx are calcareous stones, mainly calcium carbonate, and products containing lemon, vinegar or other acids will dull or etch them.^[12] Sealers do not prevent that: the Natural Stone Institute describes them as repellents and states that sealing does not make stone stain proof, only more stain resistant.^[12] Stain resistance and etch resistance are different problems. Choose marble because you accept a patina.

Ask where the slab is fabricated

Engineered quartz is stone powder bound in polymer resin, typically over 90 percent crystalline silica.^[13] Cutting it is genuinely hazardous work: 51 percent of inspected California fabrication shops had an employee exposed above the permissible limit, and silicosis among fabricators has been fatal.^[13] Asking which shop fabricates the slabs, and whether it wet-cuts under proper controls, is a good proxy for the rest of the job. For local per-square-foot pricing, use the Columbus kitchen cost estimator.

Tile and flooring: what the ratings actually mean

Tile carries a published wear rating that almost nobody checks. Glazed tile is tested under ASTM C1027, which classifies the surface from 0 to 5 by the point at which abrasion becomes visible. The figure is widely and incorrectly called a PEI rating; class 3 is typical for most interior residential areas and class 4 for most commercial spaces.^[14] For unglazed tile the measure is the abrasive wear index, and ANSI A137.1 sets a minimum of 100 for porcelain pavers.^[14] Ask for the class before falling for a dark, high-gloss floor tile.

The detail that decides whether tile lasts

Movement joints. Industry guidance requires flexible sealant — silicone, urethane or polysulfide — at perimeters and every inside corner, not grout.^[15] Grout in a corner is rigid, so it cracks and releases; floors without proper joints have tented and required full replacement.^[15] If a proposal never mentions caulk at changes of plane, ask.

Wood versus vinyl plank

The difference shows up in year twelve. Most solid wood floors can be sanded six to eight times; solid stock carries about a quarter-inch wear layer, engineered a sixteenth to a quarter, and the NWFA position is that anything under 3/32 inch should not be sanded.^[16] Luxury vinyl plank has no sandable wear layer, so it is a replacement item rather than a refinishable one. That is no reason to avoid it, but it changes the arithmetic over a twenty-year hold.

Plumbing fixtures and lighting: what wears, and what you cannot change later

Some fixture decisions reverse in an afternoon. Others sit behind tile for thirty years.

The valve is the decision; the trim is the finish

A shower valve body sits inside the wall; the visible handle and escutcheon are sold separately. Manufacturers state plainly that a rough-in valve is designed to work only with that manufacturer’s trim.^[17] Changing the look later means the same brand and series; changing brands means opening the wall. Before the valve is set, ask which platform it is and whether cartridges and trim for it are still in production.

Finish durability is a process, not a colour

Matte black and brushed gold are not one thing. Physical vapour deposition coatings are typically harder and more wear-resistant than electroplated ones, though less ductile and able to crack or peel.^[18] Other decorative finishes are organic coatings and are not comparable. The colour on a website tells you nothing about which you are buying; the specification sheet does.

A Columbus note

Columbus softens its water to an average of 120 parts per million, roughly 7 grains per gallon, which it calls moderately hard.^[19] Enough to spot polished chrome, dark matte surfaces and clear glass; brushed and honed hide it. Lighting follows the valve logic: swapping a fixture is a trim change, but moving a switch or dimmer opens drywall, so switching layouts belong in the planning sequence and on the permit set described in the permits and inspections guide.

When do selections have to be final?

Before anything is ordered — for cabinetry, weeks before demolition rather than days after it. Cabinetry is the long pole in almost every kitchen, and industry reporting names lead-time delays, shipping costs, parts and wood species availability, damaged units and tariffs as the standing procurement hurdles.^[20] Countertops add a second gate: a template cannot be taken until cabinets are set and level.

What a late selection actually costs

Two separate bills. Schedule: a crew that cannot proceed moves to another job and returns when a full day of work exists. And the change order: the price difference plus any re-work already performed against the original selection. Ohio guidance is that changes require written approval,^[7] and where unforeseen excess costs cross $5,000 the owner is entitled to notice and an estimate first.^[6]

A workable rule

Lock items in the order the trades need them, not the order you find them interesting. Valves, tub or shower base, and anything affecting rough plumbing or electric come first, because they are set before drywall. Tile and backer next. Cabinets are ordered early regardless of install date, because the order date is set by lead time. Countertops are selected early and templated late. Paint and hardware can be last. The full order of operations is in the renovation timeline guide.

What to decide, and what to ask before you sign

A selections checklist, in the order the questions arise.

1. Who supplies what, written by category into the scope of work: owner-supplied, contractor-supplied, or allowance.
2. Whether each allowance is materials-only or materials-and-labor, and whether it is delivered cost.^[2]
3. A dated selections deadline per category, tied to the order date rather than the install date.
4. The wear class on every floor tile and the finish process on every fixture.
5. The valve platform, and whether parts for it are still in production.^[17]
6. Where slabs are fabricated, and under what dust controls.^[13]
7. Who signs change orders, and in what form.^[7]

A bathroom worked through. A gut bath in a 1950s Clintonville ranch: the owner selects tile, vanity, top, mirror, lighting and trim finish; the contractor supplies backer, membrane, mortar, grout, sealant, blocking, fasteners and the valve body. The valve platform and whether the tub is replaced are settled first, because both are set before the walls close.

A kitchen worked through. The cabinet order date drives everything, and appliances must be selected before cabinets are ordered, because opening and panel dimensions come from the appliance specifications. Countertop is templated after install; backsplash can wait until the counter is in. See kitchen remodeling, bathroom remodeling and how projects are priced.

Buying locally. Central Ohio has deep tile, stone, cabinet, plumbing and lighting showrooms across Columbus, Dublin, Westerville and Hilliard, plus stone yards where slabs can be tagged individually. Two habits: tag your own slab rather than approve a sample, and take material home for a day — a finish that reads warm under showroom halogen reads grey under a north window. On new construction and custom homes the same decisions arrive as a finish schedule attached to the drawings.
