Shower Base Replacement

Indicative Investment Guide: $1,200 - $2,600

Replacing the shower base provides an opportunity to resolve ageing, damaged or poorly performing shower floors while preserving surrounding construction that remains suitable for continued service.

Where the existing wall system, waterproofing and supporting construction continue to perform as intended, replacing the shower base alone often delivers a practical outcome without introducing unnecessary reconstruction elsewhere within the bathroom.

Although the shower base forms only one component of the wet area, its condition influences drainage performance, access, appearance and compatibility with the completed shower enclosure.

Where assessment confirms deterioration remains confined to the shower base itself, Aureumus limits construction to the floor assembly rather than expanding works unnecessarily.

This installation approach preserves suitable surrounding construction while introducing only the work required to support a renewed shower base and completed shower enclosure.

The qualification criteria below explain where shower base replacement becomes appropriate, the construction it introduces, and the point at which broader floor renewal becomes the more suitable solution.

Determining Suitability.

Purpose

Where deterioration is confined to the existing shower base, replacing the floor assembly often provides the most appropriate balance between preserving surrounding construction and restoring the performance of the shower enclosure. This prevents water ingress entering into wall and floor framework including substrates.

Requirements

Appropriate application generally assumes:

• Existing shower base removal.

• Plumbing waste reconnection.

• Localised floor preparation.

• Existing wall construction remains suitable.

• Existing waterproofing outside the shower base remains suitable.

• Structural floor construction requires little or no repair.

Where deterioration extends beyond the shower base into the surrounding floor construction, broader floor renewal becomes necessary.

Limitations

This level of construction remains appropriate while deterioration is substantially confined to the shower base.

Where surrounding floor finishes, waterproofing or supporting floor construction have also deteriorated, replacing the shower base alone may no longer provide the most appropriate long-term outcome.

Applications

This level of construction is commonly encountered where:

• Existing shower bases are cracked or damaged.

• Surface wear has reached the end of its service life.

• Existing shower bases no longer suit the intended renovation.

• Drainage performance requires improvement.

• Surrounding wall construction remains suitable for continued service.

Outcome

Following installation, the completed shower provides:

• New shower base.

• Reconnected drainage.

• Renewed shower floor.

• Integrated junctions to adjoining wall finishes.

• Improved drainage performance.

• A renewed shower foundation ready for continued service.

Progression

Progression generally becomes necessary where inspection identifies:

• Deteriorated bathroom floor finishes.

• Surrounding floor renewal.

• Existing floor preparation requirements.

• Broader waterproof reconstruction.

• Bathroom floor levelling.

• Installation of a complete engineered floor system.

These conditions indicate that renewal may extend beyond the shower base, introducing an LVT Overlay before the finished shower enclosure is completed.
