DIY vs. Professional: The Better Way to Fix a Water‑Damaged Shower

Share this:

DIY, or “do-it-yourself,” refers to the practice of building, modifying, or repairing things oneself without relying on professional help, often driven by a desire for cost savings, customization, or personal satisfaction.

Social media is a popular resource for DIY guidance, with 77% of homeowners using it and reporting an average savings of $2,128 over time, but this approach can also lead to incomplete or substandard repairs.​ No wonder around 75% of homeowners attempt DIY fixes before calling professionals, yet 17% of these efforts result in additional damage, averaging $599 in extra costs per incident. 

Cost and Quality Comparison: DIY vs. Pro

DIY repairs typically have lower initial costs by avoiding labour fees, which can account for 50% or more of professional service bills. However, while DIY projects may seem more cost-effective upfront, they often result in higher overall costs due to overruns, delays, and potential non-compliance with local building codes, which could lead to fines or legal issues. 

Professional repairs, although more expensive initially, offer higher quality, durability, and come with warranties that reduce the risk of future problems. Nearly 30% of homeowners abandon DIY projects, leaving incomplete work that causes ongoing stress and disruption. For urgent or complex tasks, 63% of homeowners opt for professional services, valuing safety and reliability.

The DIY approach: What it offers and what it doesn’t

Pros:

  • Cost‑saving: For minor issues (e.g., peeling sealant, cracked grout), the immediate outlay may be modest.
  • Control: Homeowners, strata committees, or property managers can schedule and monitor the job according to their own timing.
  • Satisfaction: There’s a sense of hands‑on accomplishment.

Cons:

  • Hidden complexity: A visible crack or discoloured grout may only be the tip of the iceberg. If the waterproofing has failed, moisture may be hidden behind tiles or within the structure — becoming visible only later.
  • Risk of inadequate repair: Without specialist tools and methods, the fix may be temporary. This can lead to repeat issues or far more costly repairs down the track. For example, while some DIYers will re‑grout or apply a bead of sealant, they may not address the source or ensure correct drainage or substrate waterproofing.
  • Time and disruption: What looks like a quick patch can turn into a multi‑day project, especially if things don’t go as planned.
  • Impact on asset value and warranty: For strata or property managers, a faulty fix may result in future claims, increased maintenance, and disputes.

There are many ways you can renovate your bathroom but if you’re looking for a quick and budget-friendly fix, regrouting tiles is the key.

The DiamoSmart® System, copies of which are now used throughout the industry, was pioneered by our founder, Mark Studdert. Before its invention, Mark noticed that the old method of regrouting showers caused small but visible chips to the edges of tiles and diminished the lustre of the tiles’ edge. He designed a small diamond-tipped grouter that would eliminate these issues when regrouting bathroom tiles. Our team offers a Diamond Re-Grout Service where we strip off existing grout and replace it with a premium Epoxy grout, which is more resistant to stains, cracks, harsh weather conditions, chemicals, and climate changes than traditional grout. This makes it suitable for areas with high traffic and since it’s a waterproofing grout, it improves not only the bathroom’s aesthetics but also its functionality.

FAQ’s

The purpose of the grout is to emanate an unblemished tile appearance, while bonding the wall junctions and the floor and wall junctions – preventing wall and floor separation.

Grout mixtures must be selected carefully to make sure that dirt and other outside elements like mould and mildew will not seep into the tiles to avoid discoloration and possible leaks.

There are various ways in which installation can cause cracked grout in shower:

* If mixed with too much water concentration or additives

* If too little adhesive is used in tiles installation

* Cement-based grout can only handle the pressure for so long if a tile pulls away from the wall after the adhesive dries

Fact: Grouting is the weakest link in a tile installation.

Cracked grout in shower mainly happens due to movement between two surfaces with homes inevitably moving in tiny increments because of humidity, foundation settling, and temperature.

Even old or damaged grout can make the most beautiful looking tiles ugly and not to mention, it can cause structural damage to your home. Thus, immediate regrouting shower service is needed.

Regrouting showers and tiles is a quick and budget-friendly fix if mould has already grown into some parts of your bathroom. We highly recommend using epoxy over cement-based when regrouting tiles because it’s stronger, more durable, and only requires light maintenance.

At the first sign of grout damage, you must regrout shower tiles immediately. The longer showers are left with failing grout, the higher the chance that water damage is occurring to the wall behind your tile. The area of damage does not have to incur direct water spray during baths or showers to allow water seepage. Water that sits on the surface of tiles from shower spray or heavy steam will inevitably run behind the broken areas of your grout

Before the invention of the DiamoSmart® System, the old methods of tile regrouting caused small but visible chips to the edges of tiles and diminished the lustre of the edge of the tiles. The DiamoSmart® System eliminated this issue. Our exclusive procedure for regrouting showers is listed below:

* Remove any mouldy or deteriorated sealants such as silicon

* Strip the existing grout out of the walls * Strip out any damaged grout from the floor area

* Strip out grout from around the drain

* Prepare floor and wall junctions using our DiamoSmart® system. This system uses a diamond-tipped blade for regrouting bathroom tiles, removing the sheen from the tile edge creating a small gully in wall and floor junctions.

* Inject our SealRight sealant into the gully so it bonds the wall junctions and the floor and wall junctions – preventing wall and floor separation.

* Regrout bathroom walls and floor using commercial grade mould retardant grout

* Apply silicon to the internal areas of the shower screen

* Coat the internal shower area with our hydro barrier sealant creating an invisible glove to prevent water penetration. This sealant is painted or sprayed on the wall and floor tiles, waterproofing grout surface and beneath it. This soaks in and seals anything that is porous, such as grout lines and hairline cracks.

 

When regrouting showers and tiles, the type of grout matters and you should know that Epoxy grout is the most superior of all. Here’s why.

Unlike traditional grouts, Epoxy grout is made of two-part epoxy resins which are mixed with filler powder.

What does that mean?

Its composition makes it:

* Waterproof
* Nearly 100% resistant to stains
* Highly resistant to chemicals and physical pressure
* Doesn’t need sealing
* Low maintenance

These characteristics make Epoxy grout the best for regrouting shower and bathroom tiles. Its stain, crack and chemical-resistant properties make it suitable for areas with high traffic whilst its resistance to climate changes make it ideal for locations with harsh weather conditions, excessive amounts of humidity or severe cold. What’s even more interesting is that Epoxy grout’s colour remains constant throughout. The pigment of traditional grout can diminish easily during cleaning.

Moisture and direct water contact contribute to grout deterioration over time, and eventually, the tiles will crack. This is why you should consider regrouting shower tiles every six months. This is a quick and budget-friendly fix that can restore your bathroom’s previous glow immediately.

You should know that you need to call in a professional to do the tile regrouting for you. Even if you possess excellent handyman skills, small mistakes can lead to extensive damage to your grout and tiles. The cost to regrout shower is expensive and if the grout is not installed correctly, moisture can seep into small holes, causing mould and mildew growth, and may cause you to call for a regrout service earlier than expected.

Cement-based grout is actually the weakest link in tile installation because of its many drawbacks with the major being its porous nature. Its pores allow dirt and other outside elements to find their way into the grout, causing staining and allowing mould and grime to embed themselves into the grout, which requires an urgent regrouting shower service.

The best way to prevent grout from cracking is by using Epoxy grout which is strong, durable and requires light maintenance. Whilst it costs higher than cement-based grout, it lasts much longer, negating the cost to regrout shower.
