Straight answers to the questions Columbus homeowners ask most often.
How accurate is the estimator?
It runs the same trade hours, subcontract costs and material budgets a licensed Columbus general contractor uses to build a real estimate, at $85 an hour for self-performed work. The number is a planning range, not a national average and not a quote. Existing conditions, access and the actual selections all move it, and a formal quote confirms them on site.
Why is the range so wide?
Because the selections drive it. The estimator defaults a mid-range vanity and top to $300–$500 and a luxury one to $1,500–$4,000, and that spread repeats across eight other fixture and finish lines. Site difficulty adds another 5–35% on top of labor, subcontract and materials. Step 3 shows how each choice moves the total.
Do I have to give you my email?
No. The estimator works end-to-end without any contact information. Step 5 is optional, and it exists only for homeowners who want the itemized breakdown sent to them.
What does "tier" mean?
Tier changes the scope, not just the prices. Standard keeps the existing layout and uses stock finishes. Mid-range guts the room, tiles it and adds a waterproof membrane. High-end adds custom work and a layout change. Luxury does structural changes and top-of-the-line everything. The labor standard is the same at every tier; the difference is what gets installed.
Is labor included in the estimate?
Yes. The summary step breaks out materials and fixtures separately from labor. Labor scales with both the tier and the room size, and it is the largest single line in every tier.
Does this include permits, inspections, or design fees?
No. The ranges exclude permits and permit fees, HVAC work beyond the exhaust-fan duct run, an electrical panel upgrade, mold or asbestos remediation, window or exterior door replacement, foundation work, relocating risers outside the bathroom, appliances and water heaters. In Columbus a like-for-like fixture swap generally needs no permit; moving plumbing or electrical, or changing structure, does.
Can I use this for insurance claims or refinance appraisals?
It is a planning tool. It is a reasonable starting point for a conversation, but it is not a contractor quote and it is not an appraisal. A number on letterhead has to come from a contractor who has walked the room and written a scope of work.
