How MULTTI Handles Material Purchasing for Bathroom & Flooring Renovations
TRANSPARENCY ALL THE WAY
One of the biggest concerns homeowners have during a renovation is material cost transparency.
Questions like “Am I overpaying?”, “Who controls the purchases?”, and “What exactly am I paying for?” are common — and completely valid.
At MULTTI Construction, we believe material purchasing should be clear, documented, and fair. That’s why we follow a structured, no-markup approach and provide full visibility into what goes into your bathroom or flooring renovation.
This article explains how we handle materials, using a real bathroom renovation example, so you know exactly what to expect.
What “Materials” Really Mean in a Bathroom Renovation
Every project will have it’s list of material during the estimate process. A full, transparent and honest list will be submitted with the scope of work so the homeowner can approve and decide which material/brand he wants to go with.
We always follow the homeowners guideline, and will work with customers budget to help the decisions of what type of material fits better for their renovation.
When most people think of materials, they think of tile, fixtures, and paint.
In reality, a bathroom renovation requires much more than finishes.
Materials fall into several critical categories, and vary for each project, whether it’s include plumbing/electrical changes and etc. But so for you to have an idea of what your list might show, here it’s what we plan for:
Protection & site preparation
Framing and structural prep
Plumbing rough-in components
Waterproofing systems
Tile installation materials
Electrical components
Finishing and detailing supplies
Each category plays a role in the durability, safety, and longevity of the bathroom — even if it’s hidden behind walls.
Protection & Preparation Materials (Before Work Even Starts)
Before demolition begins, we protect your home and prepare the workspace.
This includes items like:
Plastic sheeting and floor protection
Painter’s tape and protective coverings
Heavy-duty trash bags for debris management
These materials protect adjacent rooms, flooring, and access paths — a step that’s often skipped by low-quality contractors but critical to maintaining a clean job site.
Plumbing & Structural Materials (Behind the Walls)
Adding or upgrading a shower requires proper plumbing and structural preparation.
Materials in this category include:
Framing lumber and treated bottom plates
Fire block foam and stud guards
Shower drains, P-traps, PVC piping, and fittings
PEX tubing and fittings
Pressure-balance shower valve and trim
Toilet flange, wax ring, and hardware
These components are not optional — they ensure code compliance, safety, and long-term performance.
Waterproofing System (One of the Most Important Investments)
Tile itself is not waterproof — the system behind it is.
That’s why we include:
Foam shower pan (cut-to-fit)
Foam curb
Waterproofing membrane kit
Drain waterproofing collar
Seam tape and compatible thinset
This creates a fully integrated waterproof shower system, designed to protect your home from moisture damage for the long term.
Tile & Surface Installation Materials
Installing tile correctly requires more than tile alone.
Supporting materials include:
Cement board and moisture-resistant drywall
Alkali-resistant mesh tape
Thinset, grout, spacers, and edge trims
Silicone and sealants
For this example bathroom, materials include:
Wall tile
Mosaic tile for shower floor
Bathroom floor tile
Transition strips and finishing profiles
These components ensure proper adhesion, alignment, expansion control, and clean detailing.
Electrical & Lighting Support Materials
Even small bathroom updates may require:
GFCI receptacles
Electrical wiring
Switches and connectors
These materials support safety upgrades and code compliance where needed.
Painting & Finish Materials
The final look depends on:
Primer and moisture-resistant paint
Caulking
Sandpaper and finishing supplies
Baseboards and trim
These details complete the space and protect surfaces from humidity.
What makes MULTTI different:
No markup on materials
Materials are billed at actual cost
Receipts are provided upon request
Customers can access receipts online once approved
Material pricing reflects market prices at time of estimate
If, after all purchases:
Materials cost less than estimated → the difference is applied toward labor
Materials cost more due to market fluctuation → the difference is transparently applied
No hidden fees. No inflated invoices.
Helping You Choose the Right Materials — With 3D Visualization
Choosing materials can feel overwhelming. That’s why MULTTI doesn’t just hand you a list — we guide you.
We help homeowners:
Choose the right tile for each bathroom area
Select mosaics, layouts, and finishes that work together
Coordinate fixtures and colors
Avoid materials that don’t perform well in wet zones
To make decisions easier, we provide 3D renderings showing:
Tile options
Layouts and patterns
Fixture finishes
Overall design combinations
This allows you to see your bathroom before materials are purchased — reducing mistakes and regret.
Material Guidance for Hardwood Flooring Projects
The same transparency applies to flooring projects.
For hardwood flooring, we help you choose:
The right wood species for your lifestyle
Solid vs engineered hardwood (important in Florida)
Proper plank size and layout
Finish type based on wear and maintenance expectations
We also plan underlayment, moisture barriers, and installation details before purchasing materials — ensuring performance, not just appearance.
Why This Matters to Homeowners
By managing materials this way, MULTTI ensures:
No surprise charges
No rushed decisions
No unnecessary upgrades
No corner-cutting behind walls
You know exactly what you’re paying for — and why.
