Episode 98 of Talking Architecture & Design is a 46-minute conversation with Caroma Senior Industrial Designer Luke di Michiel and GWA Head of Design and Innovation Andy Grigor. Its stated subjects are toilet design, technology, water savings, sustainability and the future direction of the toilet—not a published product test or a set of quantified engineering results.
This guide explains exactly what the episode listing establishes, how to interpret its dates and guest credentials, which Caroma product categories provide context, and what the available information cannot prove about water use or performance.

What Episode 98 is about
The episode is part of Talking Architecture & Design, a podcast associated with Architecture & Design. The publisher’s Caroma listing identifies Episode 98 as a discussion of toilets, toilet design, technology and where the “humble toilet” is heading. The title adds water savings and sustainability as central themes. You can find the publisher’s episode and supplier page at Architecture & Design’s Caroma page.
That wording matters. It presents a design conversation and a look at future direction, rather than promising a specification sheet, a laboratory comparison or a buying recommendation. The available listing does not provide a transcript, attributed guest quotations, measured flush volumes, test conditions or a product verdict.
#1 Best Overall
- COMPLETE 5-PIECE BRUSH SET FOR EVERY PAINTING TASK — Includes 1 Inch Flat, 1.5 Inch Angle, 2 Inch Flat, 2 Inch Angle Stubby, and 2.5 Inch Angle brush giving you every size professional painters use daily. Get all 5 for less than the price of a single brush from hardware store brands — professional grade performance at a fraction of the cost. Perfect for walls, trim, cabinets, doors, furniture, and detailed cutting-in work on any project.
- ZERO BRISTLE LOSS — GUARANTEED BY PRECISION ADHESIVE BONDING — Every bristle is locked in place with precision-set adhesive that keeps them in the brush — not in your paint job. The coated steel ferrule provides structural support while the adhesive bond ensures clean performance on every stroke. Premium SRT synthetic filaments load more paint and release it evenly for a smooth streak-free finish on walls, ceilings, and trim. Works with latex, oil-based paint, primer, sealer, and wood stain.
- INCLUDES THE ANGLE STUBBY MOST SETS LEAVE OUT — Professional painters know the 2 Inch Angle Stubby is the go-to brush for tight cabinet interiors, window sashes, inside corners, and detailed trim where standard angle brushes are too long. Combined with the 1.5 and 2.5 inch angle sash brushes you have precision cutting-in covered at every scale — baseboards, crown molding, door casings, and ceiling lines.
- FLAT BRUSHES FOR BROAD SMOOTH COVERAGE ON ANY SURFACE — The 1 and 2 inch flat brushes deliver even coverage on walls, furniture, shelving, doors, fences, decks, and wood surfaces. Ideal for applying primers, stains, varnishes, polyurethane, and specialty coatings. Solid wood handles provide all-day comfort and control for both professional contractors and weekend DIY homeowners tackling interior or exterior painting projects.
- TRUSTED BY PROFESSIONAL PAINTERS AND CONTRACTORS NATIONWIDE — Pro Grade delivers professional-grade results at a price that makes sense for crews who go through brushes on every job. Ideal for property managers, remodeling contractors, apartment turnover crews, maintenance teams, and commercial painting operations. Backed by thousands of verified reviews from working painters. Washable and reusable for multiple projects.
The two guests
- Luke di Michiel is identified as Caroma’s Senior Industrial Designer.
- Andy Grigor is identified as GWA’s Head of Design and Innovation for the Caroma, Methven, Clark and Dorf brands.
The guest descriptions come from the episode listing reproduced by Poddtoppen, which you can read at the Episode 98 entry. Their roles explain why the discussion is framed around industrial design and innovation, but a job title should not be treated as evidence that every claim in the episode applies to every Caroma model.
Episode details and the date discrepancy
| Detail | What the listings say | How to read it |
|---|---|---|
| Episode | 98 | The numbered installment of Talking Architecture & Design. |
| Runtime | 46 minutes | Amazon Music’s displayed duration for the listing. |
| Platform date | 17 January 2022 | The date shown on Amazon Music, not necessarily the recording date. |
| Season context | Described by Architecture & Design as the podcast’s last episode for 2021 | A publisher description of the 2021 run, distinct from a platform’s display date. |
| Guests | Luke di Michiel and Andy Grigor | Both are presented in design and innovation roles connected with Caroma. |
Amazon Music displays the episode with a 17 January 2022 date and a 46-minute runtime. Its listing is available at Amazon Music. Architecture & Design calls the installment the final podcast for 2021. These statements are not necessarily contradictory: one is platform metadata and the other describes the podcast’s season or publishing run. If you cite the episode, label the platform date as displayed rather than asserting that it is the recording date.

What the episode’s themes cover
Toilet design
“Toilet design” is broader than the visible shape of a pan or cistern. In the context supplied by the listing, it is the design problem the guests are there to discuss: how a familiar bathroom fixture is developed and how its role may change. The material does not identify a particular form, mechanism, user study or design decision, so readers should not attribute a specific innovation to either guest without hearing the episode itself.
Technology
The title and description explicitly put technology on the agenda. That signals a conversation about technological direction, not a catalogue of functions. The listing does not say which sensors, controls, connectivity features or cleaning systems were discussed, nor does it establish that a given technology is available across a product range.

Water savings
Water savings are named in the episode title, making resource use a central question. No numerical saving, litres-per-flush figure, baseline, test method or time period appears in the available descriptions. It would therefore be inaccurate to claim that the episode proves a particular percentage reduction or that any Caroma toilet achieves a stated saving based on this material alone.
Sustainability
Sustainability is also a framing theme. The listing does not break that subject into embodied materials, manufacturing, transport, service life, repairability, packaging or end-of-life treatment. Those are sensible questions for a listener to keep in mind, but they are not findings supplied by the episode description.
The future of the toilet
The publisher says the guests discuss where the toilet is ultimately heading. That future-facing framing distinguishes the episode from an installation manual. It invites design and industry questions—what users may expect, how technology could be integrated and how resource concerns might influence development—without establishing a forecast, launch timetable or market prediction.
How to use the episode as a design briefing
Because there is no detailed transcript in the available material, the most reliable way to use Episode 98 is as a structured briefing. Listen for whether the conversation supplies evidence for each of the following questions, then record the model, conditions and timeframe whenever a claim concerns performance.

- Define the design problem. Is the speaker addressing hygiene, comfort, accessibility, cleaning, installation, appearance, water use or another user need?
- Separate concept from product. Note whether a statement describes an industry direction, a prototype idea, a product family or a specific model.
- Identify the measure. For water-related claims, look for a stated volume per flush, comparison baseline, test standard and operating assumptions.
- Check the boundary. Ask whether the claim applies to one bathroom layout, one market, one generation of product or the entire brand.
- Record the trade-off. A design change may affect installation, maintenance, user control, cost or accessibility. The listing itself does not tell us what those trade-offs are, so they should not be filled in by assumption.
This approach keeps the episode useful without turning a high-level conversation into an unsupported specification sheet.
Caroma product categories mentioned in the supplier context
Architecture & Design’s supplier profile provides two concrete categories related to the episode’s smart-toilet theme:
Recommended Free Tools
| Category or example | What is established | What is not established by the listing |
|---|---|---|
| Urbane II Bidet Suites | Listed under “Smart toilets” on the Caroma supplier profile. | Specifications, water-use data, installation compatibility, current stock and independent performance. |
| Caroma LiveWell Bidet Seat | Listed as a bidet-seat product in the supplier profile. | Retail price, seller, inventory, plumbing or electrical compatibility and measured results. |
These entries are product-context examples, not endorsements or rankings. A reader considering a bidet seat or smart suite still needs the exact model documentation and an assessment of the existing bathroom. The supplier profile alone cannot establish whether a particular installation will fit, whether additional plumbing or electrical work is needed, or how the product performs in independent testing.
What the available information cannot prove
- No quantified water saving: there is no stated litres-per-flush value, percentage reduction or test result.
- No performance comparison: the material does not compare flush performance, noise, reliability, cleaning or maintenance with another toilet.
- No universal feature list: the episode title does not identify technologies shared by all Caroma toilets or bidet products.
- No installation assurance: neither the podcast listing nor supplier profile confirms compatibility with a particular pan, waste position, water connection or electrical supply.
- No current availability claim: a supplier-profile entry does not verify stock, retailer listings or pricing on a given date.
- No guest quotations: the available text is publisher-written description, not a transcript or verbatim statement from di Michiel or Grigor.
These limits are useful for readers making a purchase or writing about the episode. They mark the difference between a topic the guests are described as discussing and a result that has been documented with a number, test or quotation.
Rank #4
- Bates paint brushes come in a convenient 6 pieces with 3 flat and 3 angled bristle styles, including (1”, 1.5”, 2”) flat and (1.5”, 2”, 2.5”) angled bristles, perfect for tackling any surface painting or staining job.
- The sturdy natural bristles of each brush are designed to hold more paint, creating a smoother finish with fewer streaks and saving you time on the job.
- The lightweight wooden handles provide extra comfort and ease during long painting processes like walls, trims, cabinets, and doors.
- These versatile brushes are ready-to-use, easy to clean, and can be reused multiple times, making them economical as well as reliable tools for any painting project.
- Bates paint brushes can be used for both oil-based paints as well as latex stains and are ideal for home or commercial projects such as decks, fences or DIY painting jobs.
A practical checklist for evaluating a toilet after listening
If Episode 98 prompts you to investigate a toilet or bidet product, use the following checklist before treating a sustainability or technology claim as actionable:
- Water use: find the manufacturer’s stated water consumption and the standard or conditions behind it.
- Flush performance: look for the test method and whether results cover the waste loads relevant to your household.
- Plumbing fit: confirm pan dimensions, waste outlet position, inlet location and cistern or seat requirements.
- Electrical needs: for powered seats or smart suites, check voltage, outlet location, protection and whether a licensed electrician is required in your jurisdiction.
- Maintenance: establish which parts are user-serviceable, how consumables are replaced and where warranty support is provided.
- Accessibility: assess seat height, controls, transfer space, reach ranges and whether controls remain usable if a user has limited mobility or vision.
- Lifecycle: ask about materials, repair options, expected service life and disposal route rather than treating “smart” as synonymous with sustainable.
- Total cost: include the fixture, installation, alterations, electrical work, filters or consumables and future servicing.
The checklist supplies decision criteria; it does not assign scores to the Urbane II, LiveWell or any other model. The available sources contain no product test data from which a ranking could responsibly be built.
Why the episode is still useful without a specification table
Industrial design discussions can clarify the questions that specifications alone leave unanswered. A water-use figure, for example, is meaningful only when you know the test basis and the plumbing context. A technology feature matters only if it solves a user problem without creating an unacceptable maintenance or installation burden. A sustainability statement needs a defined boundary: operational water use is one issue, while materials, manufacturing, service and disposal are others.
Episode 98 is therefore best approached as a conversation starter for architects, bathroom renovators, product designers and technically minded homeowners. It places the toilet in a design-and-innovation discussion and points listeners toward the relationship between user experience, technology and resource use. For decisions about a specific product, supplement the episode with the current technical sheet, installation instructions, warranty terms and independent testing where available.
