Measure Your Space Accurately
Before you select a bathtub, take precise measurements of your bathroom.

Measure for Clearance: For a freestanding tub, measure the total floor area. You need to plan for adequate clearance on all sides for cleaning and easy access. A good rule of thumb is at least 4 inches of open space on all sides to ensure the tub will fit.
Check Your Path: Don't forget to measure doorways, hallways, and stairwells. A large cast iron tub won't do you any good if you can't get it into the bathroom.
Consider Bathroom Size and Building Codes

The International Residential Code (IRC) provides guidelines that local authorities often adopt, so it's wise to check your local requirements before starting a project.

Installation, Cost, and Remodeling Tips
Installing a new bathtub comes with its own set of challenges, especially when changing the size or style.
Cost Factors: The price of a bathtub goes up with size and material. Larger tubs not only cost more to purchase but also increase labor costs for installation and potentially plumbing modifications. A heavy cast iron tub might also require a contractor to reinforce the floor joists, adding to the expense.
Installation Hurdles: Swapping a standard 60-inch alcove model for another of the same size is straightforward. However, installing a 72-inch soaking tub in its place will require reframing the wall. Installing a freestanding tub where an alcove tub once was will require plumbing relocation and patching the floor and walls.
Pre-Installation Checklist:

Verify Clearances: Double-check that the uncrated dimensions for a bathtub fit your intended installation area. Tubs can fit through all doors, hallways, and stairs.
Confirm Drain Alignment: Check if your new tub's drain is on the left, right, or center, and ensure it matches your existing plumbing for the chosen bathtub. If not, budget for a plumber to move it.
Assess Floor Strength: For heavy tubs like cast iron or large, filled soaking tubs, consult a contractor to confirm your floor can support the weight. A filled 72-inch soaking tub can weigh over 1,000 pounds.
