Bathroom renovation: budget and 2D floor plan

Before requesting quotes from a plumber or tiler, scope your project: area in m², sanitary items (shower, basin, tiles) and a realistic budget range. Kodarch combines a renovation calculator and floor plan editor to visualise the renovated room: no commitment required, on phone or desktop.

How it works

  1. 1

    Estimate the budget

    Enter the area, current condition and finish level. Select items (tiling, sanitary ware, painting, flooring…) for an indicative VAT-inclusive range.

  2. 2

    Create the plan

    Carry the dimensions into the 2D editor: walls, doors, windows. Place shower, basin or bathtub to check clearances.

  3. 3

    Refine the layout

    Adjust dimensions to the centimetre, try several layouts and keep a shared reference for the whole household.

  4. 4

    Share or export

    Export a PDF technical file or send a link to a tradesperson for more accurate quotes: without redoing the survey.

Concrete scenarios

  • Full renovation

    You are redoing floor, walls and fittings: estimate the overall range, then draw the new layout (walk-in shower, vanity unit).

  • Shower replacement

    You keep the walls but replace the bathtub with a shower: check footprint and dimensions before the plumber arrives.

  • Preparing quotes

    You want to compare 2-3 tradespeople: start from a dimensioned plan and a shared budget envelope for more consistent quotes.

Frequently asked questions

Everything you need to know before creating your plan or estimating your renovation budget.

  • Does the calculator replace a plumber or tiler quote?

    No. Kodarch provides an indicative VAT-inclusive range based on area, finish and selected items. It helps frame the project before you request firm quotes from professionals.

  • Can I start without creating an account?

    Yes. You can launch the bathroom calculator and create a first plan without signing up. An account lets you save and return on mobile or desktop.

  • Are areas and dimensions accurate enough?

    Measurements are designed to prepare a quote or site visit. They remain indicative until validated on site by a qualified professional.

  • Can I share my plan with my tradesperson?

    Yes. Export a PDF file with the plan, areas and dimensions, or use link sharing depending on your project flow.

  • Does Kodarch work on smartphones?

    Yes. You can estimate and capture dimensions on your phone, then refine the layout on a larger screen.
