Last month, my client Mandy finally succeeded in buying a property, purchasing a 400-square-foot old apartment. The first thing she did after taking possession was call me: 'Chris, my bathroom is so small, damp and stuffy. Every time I shower, the whole bathroom is wet, even the toilet paper gets soaked! I heard that you need to do a "wet-dry separation," but can it really be done in such a small space?'
I have heard this question hundreds of times in my 15 years as a real estate consultant. Hong Kong property prices are high, and many starter homes have bathrooms that are only 30-40 square feet. Yet, the bathroom is the space we use most frequently every day. A poorly designed bathroom not only affects the quality of life, but also accelerates the aging of the unit, ultimately impacting the property’s long-term value. Today, let me, as an experienced professional, explain the true meaning of 'wet and dry separation' and how to create a practical and comfortable bathroom space within the compact living environments of Hong Kong.
Core Concept Analysis: What Exactly Is Wet and Dry Separation?
The Definition and Importance of Wet and Dry Separation
The so-called 'wet and dry separation' simply refers to separating the 'wet area' (shower area) from the 'dry area' (sink and toilet area) in a bathroom. This concept originates from Japan and has been increasingly valued in the Hong Kong property market in recent years, especially by middle-class families who consider wet and dry separation a top priority when renovating their homes.
:::tip Expert Opinion According to the 2023 survey data from the Hong Kong Interior Design Association, over 68% of homeowners request a wet and dry separation design when renovating. The reason is simple: Hong Kong's weather is humid, and if the bathroom remains in a 'fully wet' state for a long time, it not only easily fosters mold, but also makes the floor slippery, increasing the risk of falls, which is especially dangerous for families with elderly people or children. :::
Three Major Benefits of Separating Wet and Dry Areas
1. Improve Hygiene Levels After separating the shower area from the toilet and sink, water splashes will not spread throughout the bathroom, greatly reducing the chances of bacteria growth. This is especially beneficial for older apartments commonly found in the Hong Kong real estate market, where ventilation conditions are relatively poor; properly maintaining wet and dry separation can effectively improve the sanitary environment.
2. Extend the Lifespan of Renovations Continuous damp environments can accelerate the aging of walls, floors, and cabinets. I have seen many homeowners who did not implement wet and dry separation, and after three to five years, their bathroom cabinets began to mold and deform, requiring renovation which is an additional expense. Proper separation design can help your renovation investment retain its value.
3. Improve Usage Efficiency Imagine this: rushing to work in the morning, the family members have just taken showers, and the entire bathroom is wet; you even have to be extremely careful when brushing your teeth. With a wet and dry separation, one person can take a shower while another person can use the sink at the same time, greatly improving space usage efficiency.
Common Methods of Wet and Dry Separation in Hong Kong
In the practical application of the Hong Kong real estate market, the separation of wet and dry areas mainly has the following methods:
Glass Shower Screen: The most common and economical option, suitable for bathrooms over 40 square feet. Transparent glass does not make the space feel cramped and is easy to clean.
Shower Curtain Divider: The most economical choice, suitable for those on a budget or renting. However, be sure to choose mold-resistant materials and replace it regularly.
Half Wall + Glass: A more sophisticated approach, using brick or waterproof panels for the lower half and glass for the upper half, providing both privacy and a sense of openness.
Completely independent shower room: Requires a larger space (at least 50 square feet), suitable for luxury homes or larger units.
:::highlight Insider Tip In the Hong Kong property market, if your bathroom area is less than 35 square feet, I would recommend using an 'L-shaped glass partition' rather than a 'straight-line type.' The L-shaped design can block splashes more effectively and does not feel too oppressive visually. This is the experience I have summarized over the past decade or so while designing for clients. :::
Practical Case Sharing: Perfect Separation Can Be Achieved Even in Small Spaces
Case 1: Bathroom Renovation of a 350 sq ft Old Apartment
Returning to Mandy mentioned at the beginning of the article, her unit is a typical old building starter apartment, with a bathroom of only 32 square feet. Our renovation plan is as follows:
Problems Before Renovation:
- The bathroom has no partitions, and the whole house gets wet every time someone showers
- The old-style bathtub takes up a lot of space
- Poor ventilation, resulting in a long-term musty smell
Renovation Plan:
- Remove the old squat toilet and replace it with a standing shower.
- Install a 900mm x 900mm L-shaped glass partition.
- Move the washbasin to the entrance area to create a clear dry zone.
- Add an exhaust fan to improve ventilation.
Renovation Cost: Approximately HK$35,000 (including demolition, waterproofing, glass partitions, and sanitary ware)
Renovation Effect: After staying for three months, Mandy reported that the bathroom is not only drier, but also saves on electricity bills (no need to keep the dehumidifier running), and because the space is well-planned, it actually feels more spacious visually than before.
Case 2: Upgrade Renovation of a 500-Square-Foot New Property
Another client, Tommy, purchased a unit in a new development. The developer's standard renovation already included basic glass partitions, but he wanted it to be done better.
Upgrade Plan:
- Replace the original clear glass with "Changhong Glass" (textured glass) to increase privacy while maintaining transparency.
- Install a "water barrier" in the shower area to further prevent water from flowing out.
- Use "wood-look tiles" for the dry area floor and "anti-slip stone-look tiles" for the wet area floor to visually create clear zoning.
- Add a "warm air dryer" to quickly dehumidify after showering.
Upgrade Cost: Approximately HK$28,000
:::success Experts recommend In the Hong Kong property market, the standard finish quality of new developments is uneven. Even if wet and dry areas are separated, it is often done in a way that is 'as if not done at all.' If the budget allows, it is recommended to carry out targeted upgrades after taking possession, which is definitely worth investing in the long run. :::
Real Data: The Impact of Wet and Dry Separation on Property Value
Based on the second-hand property transaction data I have handled over the past three years, for units in the same estate with the same area, those with properly separated wet and dry bathrooms have an average transaction price 2-3% higher. Although it may not seem much, for a unit priced at 6 million, that amounts to a difference of 120,000-180,000. More importantly, when listing the property, it is easier to attract buyers, and the average listing period can be shortened by 15-20 days.
Notes and Risks: Avoid These Common Pitfalls
Misconception 1: Thinking that installing a glass partition solves everything
Many homeowners think that installing a glass partition means they have properly separated wet and dry areas, but they find that the floor still often gets wet. So, where is the problem?
Frequently Asked Questions:
- The glass screen is too small, causing water to splash out from the sides
- No water stop strip is installed, causing water to flow onto the floor
- The floor slope is insufficient, preventing water from draining properly
- The silicone sealant has aged, resulting in poor sealing
:::warning Guide to Avoiding Pitfalls When installing a glass partition, be sure to ensure:
- The screen height should be at least 1800mm (do not make it 1500mm just to save money).
- The width should cover the entire shower area, leaving at least 100mm of overlap.
- The floor must be equipped with a 'stone water stop strip' or a 'stainless steel water stop strip'.
- Check the silicone sealant every year, and replace it immediately if aging is found.

Misconception 2: Ignoring the Importance of Waterproofing Work
In renovation disputes in the Hong Kong property market, bathroom leaks are one of the most common problems. Many homeowners focus only on surface design and neglect the most basic waterproofing work.
Key Points of Waterproofing Work:
- Waterproof Layer Height: The waterproofing on shower area walls should reach at least 1800mm, and other walls at least 300mm.
- Waterproof Material: It is recommended to use "two-component polyurethane waterproof coating," which is more durable than traditional asphalt waterproofing.
- Water Retention Test: After waterproofing is completed, a 48-hour water retention test must be conducted to ensure there are no leaks.
- Floor Drainage: Ensure the floor has a 1-2% slope so that water can flow smoothly towards the drain.
I have seen many homeowners, in order to rush the construction schedule, treat waterproofing work carelessly. As a result, leaks start occurring just six months after moving in, requiring demolition and reconstruction, resulting in heavy losses.
Misconception Three: Blindly Chasing the 'Japanese Four-Part Separation'
In recent years, the Hong Kong property market has seen the rise of the 'Japanese-style four separations' concept (completely separating the bathroom, toilet, sink, and washing machine), but this design requires at least 80-100 square feet of space. Many homeowners, seeing beautiful photos online, want to copy it, only to find that it is simply not suitable for Hong Kong's tiny living spaces.
Practical Recommendations:
- If the bathroom is less than 50 sq ft, a basic 'wet and dry separation' is enough.
- For spaces of 50-70 sq ft, consider a 'three-way separation' (shower, toilet, and sink separated).
- Only luxury units above 70 sq ft are suitable for 'four-way separation'.
:::tip Insider Tip In the Hong Kong property market, practicality is always more important than aesthetics. Rather than blindly pursuing Japanese-style design, it is better to create the most suitable plan based on the actual situation of your unit. Remember: for affordable first-time homes, the most important thing is to live comfortably, not to take photos for social media. :::
Misconception Four: Choosing the Wrong Glass Material
There are mainly three types of shower glass on the market: ordinary glass, tempered glass, and laminated glass. Many homeowners choose ordinary glass to save money, but this results in safety hazards.
Glass Selection Recommendations:
- Tempered Glass: Most commonly used, 4-5 times stronger than ordinary glass, and even if broken, it shatters into small pieces, making it safer.
- Laminated Glass: Consists of a layer of film between two layers of glass; even if broken, it will not scatter. It is the safest but more expensive.
- Ordinary Glass: Absolutely not recommended for shower screens.
Price Reference (calculated for 900mm x 1800mm):
- Tempered Glass: HK$2,500-3,500
- Laminated Glass: HK$4,000-5,500
- Ordinary Glass: HK$1,500-2,000 (not recommended)
Summary: Small Investment, Big Return
After 15 years of experience as a real estate consultant, I can confidently tell you: renovating the bathroom with a wet-dry separation is one of the most cost-effective investments among all home improvement projects.
Key Points Review:
- Separating wet and dry areas is not just an aesthetic issue, but also relates to hygiene, safety, and property value preservation.
- Even a small bathroom of 30-40 sq ft can achieve effective separation if designed properly.
- Renovation costs are approximately HK$25,000-40,000, but can increase property value by 2-3%.
- Waterproofing work is fundamental and must not be neglected.
- Choose a solution suitable for your own unit; do not blindly follow trends.
For homeowners who have just moved in, you might think, 'The renovation budget is already tight, and I still have to do wet and dry separation?' But believe me, this money is definitely worth spending. A well-designed bathroom can not only improve your daily quality of life but also become a selling point that attracts buyers when you put your property on the market in the future.
In Hong Kong's real estate market, where every inch of land is precious, every inch of space must be used effectively. Rather than spending money on flashy but impractical decorations, it is better to invest in practical designs that can truly improve the quality of life. Remember: good renovations are not about being the most expensive, but about being the most suitable for yourself.
