Most homeowners embarking on any relatively ambitious home remodeling project need to have a general sense of the cost before taking the first step. It is possible to plunge into painting the living room or self-installing vinyl flooring in a small bathroom, all without tabulating project costs, since materials cost is typically low and the labor is free. But medium or large projects like additions, basement finishing, bathroom and kitchen remodels, and major plumbing remodels usually come with high enough costs that planning and preparation are necessary.

While no one can give you a firm remodel cost estimate without seeing your exact situation, it is possible to hazard a few rough figures for many of the most desired projects.

House and Room Additions

House additions can be as simple and low-cost as sunrooms shipped to you by freight delivery and assembled on a do-it-yourself basis. At the other end of the spectrum are full-scale stick-built house additions that substantially add to your home's resale value.

  • Multi-room house addition: $150,000 to $500,000
  • Primary suite room addition: $123,000 to $256,000
  • Enclosing a porch: $7,000 to $16,000
  • Small sunroom (9 feet by 15 feet): $15,000, not including installation
  • Large sunroom (24 feet by 15 feet): $23,000, not including installation

About This Term: Primary Suite

Many real estate associations, including the National Association of Home Builders, have classified the term "Master Bedroom" (or "Master Suite") as discriminatory. "Primary Bedroom" is the name now widely used among the real estate community and better reflects the purpose of the room.

Basement Conversions

A home's basement might at first appear to be an easy remodeling job. But when you factor in the need to deal with complexities like electrical, plumbing, and HVAC systems, along with the sheer magnitude of all of that drywall and flooring and possibly the sticky legalities of turning the space into a rental unit, you end up with a project with costs approaching that of a small room addition.

  • Finish a basement with a proprietary basement finishing system: $50,000 to $75,000
  • Finish a basement by scratch with a contractor: $55,000 to $100,000
  • Do-it-yourself basement finishing by scratch: $15,000 to $25,000

Bathroom Remodels and Additions

Bathroom remodels are a great do-it-yourself project, especially if dealing with a second or smaller bathroom. When plumbing is involved, costs always sharply rise. Moving plumbing fixtures such as the tub, shower, or toilet will cause prices to rise even more.

  • Surface bathroom remodel: $1,000 to $16,000
  • Half bathroom remodel: $4,500 to $26,000
  • Full bathroom remodel: $19,000 to $62,000
  • Bathroom addition built onto the side of your house: $45,000 to $84,000

Kitchen Remodeling

A newly remodeled kitchen is the dream of many homeowners. Due to the complexity of this project, many homeowners who are otherwise adept at home remodeling often still choose to hire a contractor. Because kitchen remodels involve high-priced materials such as cabinets and appliances, even do-it-yourself kitchen remodeling can be a costly project. Repainting your cabinets or installing used cabinets is one way to drastically bring down the cost of kitchen remodeling.

  • Full-scale contractor-driven kitchen remodeling: $21,000 to $126,000
  • Full-scale do-it-yourself kitchen remodeling: $20,000 to $50,000
  • Basic surface-level kitchen remodeling: $2,000 to $20,000

Electrical Repairs and Remodels

Doing your own electrical work will substantially lower the estimate. Not all electrical work can or should be performed by homeowners. Heavy-ups are rarely completed by homeowners, as well as any work upstream of the service panel. Running new electrical circuits and hooking them into the service panel can be done by a homeowner or by an electrician. Replacing an outlet is usually a do-it-yourself job.

  • Heavy-up (increase electrical service to 200 amps): $1,000 to $1,500
  • Running separate electrical circuits in open walls: $250 to $400 per circuit for an electrician; $25 on a do-it-yourself basis
  • Replacing an outlet by yourself: $2

Plumbing Remodels and Repairs

Most homeowners tend to hire professional, licensed plumbers to take on plumbing projects and repairs. However, with the advent of PEX pipes and push-fit connectors, homeowners have been doing more plumbing repairs than ever before. Projects like installing a water heater or a sump pump can be done by the homeowner.

  • Install a new water heater: $800 to $1,500
  • Install a new septic system: $4,000 to $6,000
  • Install a sump pump, not including the installation of an outlet: $500 to $700
  • Install a french drain and sump pump: $4,000 to $5,500
  • Self-install a kitchen faucet: $50 to $300
  • Connect copper pipes by yourself with a push-fit connector: $5

Installing Flooring and Floor Repair

Flooring installation encompasses both worlds, do-it-yourself and professional. Laminate flooring, plank and tile vinyl flooring, and even small-scale ceramic or porcelain tile installations are easily accomplished by do-it-yourselfers. Yet professionals are nearly always called in to install wall-to-wall carpeting, install large expanses of tile flooring, or to install hardwood flooring.

  • Sanding and finishing a hardwood flooring: $3 to $5 per square foot
  • Installing a ceramic tile floor: $15 to $28 per square foot
  • Installing a vinyl tile floor: $4 to $6 per square foot
  • Installing wall-to-wall carpet: $5 to $12 per square foot
